`C_6H_5 CHO +CH_2 CH =CHCO overset( overset(Oh^(-))to A ` the product 'A' is

A

`C_6 H_5 CH = underset(CH_2- CH_3 ) underset(|)C-CHO`

B

`C_6 H_5 -CH=CH -CH =CH -CHO`

C

`C_6 H_5 (CH=CH)_3 CHO`

D

`C_6 H_5CH = underset(CH_3) underset(|) C-CH_2 CHO`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_6 H_5 - overset(O) overset(||)C -H +H_2 -CH -CH -CH =CH -CHO to C_6 H_5 -CH =CH -CH -CHO`
