Polarization in acrolein as:...

Polarization in acrolein as:

A

`overset (-delta) CH_2 = CH - overset (+delta)C = O`

B

`overset (-delta) CH_2 = CH - CH = overset (+delta) O`

C

`overset (-delta)CH_2 = overset(+delta)CH - CH = O`

D

`overset (-delta)CH_2 = CH - CH = overset (-delta)O`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `O` atom is more `EN` than `C` atom, so it acquires `(-delta)` charge and `C` atom acquires `(+ delta)` charge which is transferred to the last `C` atom.
