Which of the following statements is correct in relation to the halogenation of alkane?
A
The reactivity of chlorine is less than bromine towards alkanes.
B
For photochemical chlorination of methane, 
is formed in slowest step.
is formed in slowest step.
C
Free radicals are pyramidal intermediate, stabilised by hyperconjugation and resonance.
D
Bromine has much higher regioselectivity than chlori in abstracting 
hydrogen.
hydrogen.
Text Solution
Verified by ExpertsThe correct answer is:
D
is more selective in its reactions and prefers to react with the weaker 
bonds. The strength of 
varies slightly depending on the hydrogen in primary, secondary or tertiary compound. Bromination is 1640 times more likely to occur at 
position than 
. Chlorination is 5.2 times more likely to occur at 
position than 
. Hence, bromine atom has much higher regioselectivity than chlorine in abstracting 
hydrogen.
