grignard reagent + alkyl halide

can someone explain this to me? I've never seen a grignard reagent reacting with an alkyl halide before

@Oh_Gee
Grignard just makes a strong nucleophile.

In the first reaction, the Grignard attacks (adding methyl group while getting rid of a Cl).

In the second reaction, Oh- attacks (adding OH while getting rid of the second Cl).

The carbon at the center is now bonded to
1) H
2) OH
3) CH3
4) CH3

There are 2 CH3 groups and 1 OH group so that is a secondary alcohol.

is there a chance the grignard could react twice ?

Well you only have 1 molecule here (I think) so no.

In real life, probably.

Just think of Grignards as carbanions for ALL organic reactions.

Something I wanted to remind ppl, a Grignard reagent acts like a base first then a nucleophile.

what implications could that have? i've only seen it act as a nucleophile
