Vedclass · Answer

(B) Acrolein is $CH_2=CH-CH=O$. Due to the resonance effect (electromeric effect),the $\pi$-electrons shift towards the more electronegative oxygen atom. The structure can be represented as $CH_2=CH-CH=O \leftrightarrow \mathop C\limits^{\delta + } H_2-CH=CH-\mathop O\limits^{\delta - } $. However,considering the polarization across the conjugated system,the terminal carbon $CH_2$ acquires a partial positive charge due to the electron shift towards the oxygen atom.

Which of the following represents the polarization of electrons in acrolein?
