Q. Consider the following reactions,
I. $CH_{2} = CHOOH \xrightarrow{\Delta } CH_{2} = CH_{2}$
II. image
III. $CH_{3}CH(COOH)_{2} \xrightarrow{\Delta} CH_{3}CH_{2}COOH$
In which cases, parent compound loses its functional group in preference?

Organic Chemistry – Some Basic Principles and Techniques

Solution:

I. $\overset{3}{C}H_{2} = \overset{2}{C}H \overset{1}{C}OOH \rightarrow \overset{2}{C} H_{2} = \overset{1}{C}H_{2}$
$-COOH$ loses its preference

$— COOH$ loses its preference

$— COOH$ does not lose its preference
