Which of the following is not the correct order of stability?

A

`CH_(3)-overset(oplus)(CH_(2)) gt CH_(2)=overset(oplus)(CH)`

B

`CH_(3)-bar(C)H_(2) lt CH_(2)=bar(C)H lt HC equiv bar(C)`

C

`R_(2)N-overset(oplus)(CH_(2)) gt R-NH-overset(oplus)(CH_(2))`

D

`R-O-overset(oplus)(CH_(2)) lt R-S-overset(oplus)(CH_(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
`R-O- Coverset(oplus)(H_2)` is stabilized by resonance
`R - underset( * * )overset(* *)O- CH_2 harr R - overset(oplus)(O) = CH_2`
