Polarisation of electrons in acrolein may be written as :

Options

A. `overset(-delta)(CH_(2))=CH-CH=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

D

Explanation

Oxygen is highly electronegative than carbon, so it acquires partially negative charge and carbon atom acquire partially positive charge which is transferred to the last carbon atom.
