Organic Chemistry Basics 2 Question 49

49. Polarisation of electrons in acrolein may be written as

(1988, 1M) $\mathrm{H}_{2}^{\delta-} \mathrm{C}=\mathrm{CH}-\stackrel{|}{\mathrm{C}} \stackrel{|}{\mathrm{C}}-\mathrm{H}$

(b) $\stackrel{\delta-}{\mathrm{H}{2}}=\stackrel{|}{=} \mathrm{CH}-\mathrm{C}-\mathrm{H}$ c) $\mathrm{H}{2} \mathrm{C}=\stackrel{\delta+}{\mathrm{C}} \stackrel{\stackrel{O}{|}-\mathrm{O}}{\mathrm{C}}-\mathrm{H}$

(d) $\stackrel{\delta+}{\mathrm{H}_{2} \mathrm{C}}=\mathrm{CH}-\mathrm{C}-\mathrm{H}$
