The order of susceptibility of nucleophilic attack on aldehydes follows the order

A

`1^(@) gt 3^(@) gt 2^(@)`

B

`1^(@) gt 2^(@) gt 3^(@)`

C

`3^(@) gt 2^(@) gt 1^(@)`

D

`2^(@) gt 3^(@) gt 1^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`R-overset(+delta)underset(O)underset(||)(C )-H,` Susceptibility of nucleophilic attack on aldehyde is decreased by elecron releasing effect of R group. Decreasing order of aldehyde towards nucleophilic attack is `1^(@) gt 2^(@) gt 3^(@) R` group.
