Write hydrocarbon radicals that can be formed as intermediates during monochlorination of 2-methylpropane ? Which of them is more stable? Give reasons.

Explanation

2-methylpropane gives two types of radicals.
`CH_(3)-underset(2-"methyl propane")overset(CH_(3))overset(|)(CH)-CH_(3)rarrCH_(3)-overset(CH_(3))overset(|)underset((i))underset(.)C-CH_(3) "and"CH_(3)-overset(CH_(3))overset(|)underset((ii))(CH)-overset(.)(CH_(2))`
Radical (I) is more stable because it is `3^(@)` free radical and stabilised by nine hyperconjugative strutures (as it has 9 `alpha` -hydrogens)
Radical (II) is less stable because it is `1^(@)` free radical and stabilised by only one hyperconjugative structure (as it has only 1 `alpha`-hydrogen)
