JEE Main Chemistry question

Polarization of electrons in acrolein () may be written as:

(A)
(B)
(C)
(D)Correct

Answer: (D)

Solution

Oxygen is far more electronegative than carbon, so it draws electron density toward itself through the conjugated system: CH_2=CH-CH=O \leftrightarrow {}^{+}CH_2-CH=CH-O^{-}. This resonance places the negative charge on O and, correspondingly, a partial positive charge on the terminal
