Solution
The correct option is B
First we should convert the newman projection to normal projection for better clarification.
The given compound is 2-methyl propane.
For photochemical halogenation (bromination), the rate of the reaction is directly proportional to the stability of the intermediate formed.
The intermediates formed in photochemical halogenation is free radical.
We know that the stability of free radical is in the order,
Tertiary radical > Secondary radical > Primary radical
Here, the bromination occurs at 2-position because the radical formed here is tertiary and it stabilised by 9α-hydrogens.
Hence, the major product of the reaction is (b).
