Assertion: Alkyl halides form alkenes when heated above `300^(@)`C
Reason `Ch_(3)CH_(2)` I reacts slowly with strong base when compared to `CD_(3)CH_(2)` i.

Options

A. If both assertion and reason are true and the reasone is the correct explanation of the assertion .
B. If both assertion and reason are true but reason is not the correct explanation of the assertion .
C. If assertion is true but reasone is false
D. If assertion is false but reason is true .

Answer

C

Explanation

`CH_(3)CH_(2)` I reacts more rapidly with strong base in comparison to `CD_(3)CH_(2)` I the elimination of HI (or DI) in presence of strong base shown `E_(2)` elimination The rate determining step involves the breaking up of `C-H` (or C-D) bond the `C-D` bond being stronger than `C-H` and thus elimination is faster in case of `CH_(3)CH_(2)` I .
