Question

Polarization of electrons in acrolein may be written as:
(a) δ- δ+
C H₂ = CH — CH = O
(b) δ- δ+
C H₂ = CH — CH = O
(c) δ+ δ-
C H₂ = CH — CH = O
δ- δ+
(d) C H₂ = CH— C H = O

Answer 2

Option C is correct.

Explanation:

This is because of -M effect of -CHO.

Polarization is occur in following way.

CH₂=CH-CH=O

           ⇵

⁺CH₂=CH-CH-O⁻

   δ+                 δ-

So option c is correct.
