Answer 1

Benzylic halide is that alkyl halide in which there are one or more halogen atoms attached on benzylic carbon and benzylic carbon is the c atom attached directly to the benzene ring.

Complete step by step answer:
The carbon atom which is directly attached to the $s{{p}^{2}}$ The hybridized carbon of the benzene ring is known as the benzylic carbon.
If any of the halogen atoms is found to be attached with the benzylic carbon atom, then that halogen derivative is known as benzylic halide.
For example :

This is Benzyl chloride and it is an example of benzylic halide.
Out of the
and

Is known to be an example of benzylic halide. As in this derivative, the two chlorine atoms are attached with the benzylic carbon.
Whereas,
In

The one chlorine atom is attached to the carbon that is next to the benzylic carbon and not with the benzylic carbon itself.
an example of benzylic halide is,

Note: Don’t get confused with the term benzylic carbon. Basically, benzylic position is the neighbouring lotion to an aromatic ring that can conjugate with the aromatic ‘pi’ system.
