Question

Cyclohexene treated with ethyl magnesium than hcl product is

Answer 1

Answer:

ethane.

Explanation:

the reaction is addition of Grignard reagent on alkene, followed by hydrolysis.

we know that Grignard reagent abstracts a proton donating group.

that is when GR reacts with water i.e.

H-OH , we get R-H (alkane) and MgXOH

(symbols with their usual meaning).

Similarly , alkynes and , rarely alkenes too, being acidic are proton donars.

thus cyclohexene will donate the proton to ethyl group and will get attached to

-MgX group. after getting the proton ethyl group will become ethane.
