Question

The ease of substitution of H by nitro group in alkane follows the order
A. `3^(@)H lt 2^(@)H lt 1^(@)H`
B. `3^(@)H gt 2^(@)H gt 1^(@)H`
C. `3^(@)H lt 2^(@)H gt 1^(@)H`
D. `3^(@) H gt 2^(@)H lt 1^(@)H`.

Answer 1

Correct Answer - B
Nitration of alkane at `100^(@)C` follows free radical mechanism. The ease of replacement of `H^(@)` by `NO_(2)` follow the stability order of the free radical.
