Organic Chemistry – Some Basic Principles and Techniques
A
$CH\equiv CH>CH_{3}-C\equiv CH>CH_{2}=CH_{2}>CH_{3}-CH_{3}$
50%
B
$CH\equiv CH>CH_{2}=CH_{2}>CH_{3}-C\equiv CH>CH_{3}-CH_{3}$
0%
C
$CH_{3}-CH_{3}>CH_{2}=CH_{2}>CH_{3}-C\equiv CH>CH\equiv CH$
50%
D
$CH_{2}=CH_{2}>CH_{3}-CH=CH_{2}>CH_{3}-C=CH>CH\equiv CH$
0%
Solution:
Solution; Acidic nature $ \propto s\% \propto \frac{1}{+ I}$
$\underset{s \%}{C H}\equiv \underset{\overset{s p}{50 \%}}{C H}>\underset{+ I}{C H_{3}}-C\equiv \underset{\overset{s p}{50 \%}}{C H}>CH_{2}=\underset{\overset{s p}{33 \%}}{C H_{2}}>CH_{3}-\underset{\overset{s p}{25 \%}}{C H_{3}}$
