An allylide on hydrolysis gives `C_3H_4` (allylene).The alkaline earth metal cation of allylide dissolves in dry ether in presence of alkyl halide to form Grignard's reagent. The allylide is

A

`MgBr_2`

B

`Ca_2C_3`

C

`Mg_2C_3`

D

`Ba_2Ca_3`

Text Solution

Verified by Experts

The correct Answer is:
C
The alkaline earth metal is Mg and the allylide is `Mg_2C_3`. Mg forms RMgX a Grignard reagent with R-X (alkyl halide) in presence of dry ether.
