R-CH(2)-C Cl(2)-R overset(Reag ent)rarrR...

`R-CH_(2)-C Cl_(2)-R overset(Reag ent)rarrR-C-=C-R`
The reagent is

A

`Na`

B

`HCl` and `H_(2)O`

C

`KOH` in `C_(2)H_(5)OH`

D

`Zn`

Text Solution

Verified by Experts

The correct Answer is:
c
`R-CH_(2)-C Cl_(2)-R" "overset(KOH+C_(2)H_(5)OH)rarrR-C-=C-R+2HCl`
The reaction is an example of dehydrohalogenation. Hence, alcohilic `KOH` is used as a reagent.
