In free radical halogenation of alkane, the first step of propagation is exothermic when Cl₂ is used while it is endothermic when Br₂ is used. Also chlorination occur at very fast rate, hence very less selective while bromination occur at very slow rate, occurs selectively where most stable free radical is formed.

The correct statements regarding free radical chlorination and bromination reaction of alkane are:

First Propagation Step:
b) The first propagation step is endothermic in bromination reaction and exothermic in chlorination reaction.

In free radical halogenation reactions, the first propagation step involves the homolytic cleavage of the halogen molecule (X2) to generate two halogen radicals (X•). This step is endothermic because it requires energy to break the relatively strong bond in the halogen molecule. In bromination, the first propagation step is endothermic as bromine has a higher bond dissociation energy compared to chlorine. On the other hand, in chlorination, the first propagation step is exothermic as chlorine has a lower bond dissociation energy.

Reactivity and Selectivity:
c) Chlorination reaction is a more reactive process but very less selective, and the reverse is true for bromination.

Chlorination reactions are generally more reactive compared to bromination reactions. This is because chlorine radicals are more reactive and have a higher rate of reaction with alkanes. However, chlorination reactions are less selective as they can lead to the formation of multiple products due to the relatively high reactivity of chlorine radicals.

On the other hand, bromination reactions are less reactive compared to chlorination reactions. Bromine radicals are less reactive and have a lower rate of reaction with alkanes. However, bromination reactions are more selective as they tend to produce fewer side products and exhibit a higher degree of regioselectivity.

Overall, chlorination reactions are faster and less selective, while bromination reactions are slower but more selective.

To summarize:
- The first propagation step is endothermic in bromination and exothermic in chlorination.
- Chlorination reactions are more reactive but less selective.
- Bromination reactions are less reactive but more selective.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:Benzene ring in aniline is highly activated. This is due to the sharing of lone pair of nitrogen with the ring which results in increase in the electron density on the ring and hence facilitates the electrophilic attack. The substitution mainly takes place at ortho and para positions because electron density is more at ortho and para positions. On reaction with aqueous bromine all the ortho and para positions get substituted resulting in the formation of 2,4,6-tribromoaniline. To get a monobromo compound, the amino group is acetylated before bromination. After bromination, the bromoacetanilide is acid hydrolysed to give the desired halogenated amine.In the following questions, a statement of assertion followed by a statement of reason is given.
