Question

Polarisation of electrons in acrolein may be written 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`

Answer 1

Correct Answer - 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.
