The radical halogenation of 2-methyl propane gives two products (CH_(3))_(2)CHCH_(2)X_(("minor")) and (CH_(3))_(3)CX_(("major")). Chlorination givs larger amount of the minor product than the bromination because

Answer»

BROMIDE is more reactive than chlorine and is able to attack the less reactive `3^(@)C-H`
Brominie atoms are less reactive (more selective) than chlorine and preferentially atack the weaker `3^(@)C-H` bond.
The METHYL GROUPS are more HINDERED to attack by the larger bromine atom.
Bromination is REVERSIBLE and more stable `3^(@)-` alkyl bromide is formed exlusively.

Solution :Chlorine is more reactive, less selective bromine is less reactive, more selective
