The yield of alkyl bromide obtained as a result of heating the dry silver salt of carboxylic acid with bromine in CCI4 is

Detailed Solution for Test: Methods of Preparation of Haloalkanes and Haloarenes (January 25) - Question 2

The reaction follows free radical mechanism and alkyl free radical is formed in the propagation step as



Hence, stability of alkyl free radical (3° > 2° > 1°) determine the reactivity.

Which is incorrect about Hunsdiecker's reaction?

Detailed Solution for Test: Methods of Preparation of Haloalkanes and Haloarenes (January 25) - Question 3

Except F2, almost all halogens react with RCOOAg giving alkyl halide via Hunsdiecker reaction.

With l2 if RCOOAg is in excess, R— I formed in the first step reacts further with unreacted salt to give ester as
R—COOAg + R—I → R—COOR + AgI

Choose the correct statement(s) from the following regarding free radical chlorination and bromination reaction of alkane.
Detailed Solution for Test: Methods of Preparation of Haloalkanes and Haloarenes (January 25) - Question 5

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.
