Less reactivity of saturated hydrocarbons is due to the presence of single bonds between carbon atoms. Paraffins (alkanes) may have straight chain or branched chain isomers which have different parent names.

Why saturated hydrocarbons are less reactive than unsaturated hydrocarbons?

The unsaturated hydrocarbons are more reactive due to the presence of double and triple bonded carbon atoms as these are weaker than the single bonded saturated hydrocarbons due to the presence of weaker pi bonds and thus, when a reaction takes place, these unsaturated hydrocarbons break down easily as compared to ...

Why are saturated hydrocarbons unreactive?

Saturated hydrocarbon have only sigma bonds, which are very stable and difficult to break and hence these are unreactive. Saturated hydrocarbons do contain double and triple bonds that make molecule reactive for the addition reaction and hence these do not undergo addition reaction.

Why saturated molecules are less reactive than unsaturated molecules?

Saturated hydrocarbons are generally less reactive than unsaturated hydrocarbons because unsaturated hydrocarbons have electron-rich pi bonds that are...

Why are saturated organic compounds less reactive?

Saturated hydrocarbons are molecules made entirely of single carbon-carbon bonds; they cannot incorporate additional atoms into their structure, thus they are said to be saturated. These molecules, called alkanes, are stable and not very reactive.

Why single bond is saturated?

Their carbon-hydrogen bonds are also single covalent bonds. They are called saturated compounds because all the four bonds of carbon are fully utilised and no more hydrogen or other atoms can attach to it. Thus, they can undergo only substitution reactions. ... These saturated hydrocarbons are called as alkanes.

Are saturated hydrocarbons less reactive?

Less reactivity of saturated hydrocarbons is due to the presence of single bonds between carbon atoms. Paraffins (alkanes) may have straight chain or branched chain isomers which have different parent names.

Why are double bonds more reactive?

Double bonds are often found in alkenes and ring structures, where the double bond gives more stability due to resonance. ... They are more reactive than single bonds because they are more electron rich.

Is benzene saturated or unsaturated?

Benzene is unsaturated. This is due to the presence of alternate double bonds between the carbon atoms.

Are saturated compounds not very reactive?

Overall, saturated compounds are less reactive than unsaturated compounds.


Why are alkenes called unsaturated hydrocarbons Class 11?

Alkenes (C=C) have double bonds in their carbon atoms in hydrocarbon chain while alkynes have C-C triple bond in their structures. So these are known as unsaturated hydrocarbons while alkanes are saturated hydrocarbons having C-C single bond.

When an unsaturated hydrocarbon completely undergoes addition the product is?

An unsaturated hydrocarbon with formula of CXHY can have 2X+2−Y hydrogen atoms at most added to it. This will make the molecule become saturated.

Which formula represents a hydrocarbon with a triple covalent bond?

Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings). Alkynes undergo many of the same reactions as alkenes, but can react twice because of the presence of the two p-bonds in the triple bond.

Why is benzene not unsaturated?

(Hexane, the saturated hydrocarbon with six carbon atoms has the formula C6H14—eight more hydrogen atoms than benzene.) However, despite the seeming low level of saturation, benzene is rather unreactive. It does not, for example, react readily with bromine, which, is a test for unsaturation.

Are alkanes unsaturated?

Ethene, C2H4, is an example of an unsaturated hydrocarbon. ... Alkanes are saturated hydrocarbons because each member of the family has the maximum number of hydrogen atoms per carbon atom in its molecular formula. Alkenes have the general formula CnH2n, and are examples of unsaturated hydrocarbons.


How do you know if a compound is saturated or unsaturated?

In terms of degrees of unsaturation, a molecule only containing single bonds with no rings is considered saturated. Unlike saturated molecules, unsaturated molecules contain double bond(s), triple bond(s) and/or ring(s).

Which is more reactive single or double bond?

Double bonds are often found in alkenes and ring structures, where the double bond gives more stability due to resonance. They are more reactive than single bonds because they are more electron rich.

Is double bond stronger than single bond?

Experiments have shown that double bonds are stronger than single bonds, and triple bonds are stronger than double bonds. Therefore, it would take more energy to break the triple bond in N2 compared to the double bond in O2.

Why are alkanes not reactive?

Alkanes do not react with most reagents for two reasons. First, carbon‐carbon and carbon‐hydrogen single bonds are very strong due to good orbital overlap. Second, the carbon‐hydrogen bonds make alkane molecules neither acidic nor basic because the electronegativity of both elements is very similar.

Are alkynes saturated?

Like alkenes, alkynes are unsaturated because they are capable of reacting with hydrogen in the presence of a catalyst to form a corresponding fully saturated alkane. ... Because alkynes possess two π bonds per molecule, they are said to contain two elements of unsaturation.

Why alkane is saturated?

Alkanes are known as saturated molecules because other atoms cannot add to them. ... Being saturated means the alkane molecules have no C=C double bonds, only carbon–carbon single bonds, and so alkanes combined with the maximum number of atoms i.e. no atoms can add to it.

Which hydrocarbon is less reactive?

Alkanes are the simplest and least reactive hydrocarbon species containing only carbons and hydrogens.

Is single bond saturated?

Single bonds themselves are not saturated, but an organic molecule composed of only single bonds is said to be saturated.

Why are they called saturated?

They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. ... In this compound, named ethane, each carbon atom is bonded to three hydrogen atoms.

Is single bond stable?

A single bond is formed when one pair of electrons are shared between two atoms. This bond type is relatively weak and has a smaller electron density than a double bond and a triple bond, but is the most stable because it has a lower reactivity level. It means that the loss of electrons to atoms is less susceptible.
