Q. The basic strength of $CH \equiv \overline{C,}CH_{2} = \overline{C}H,CH_{3}\overline{C}H_{2}$ I II III Will be in order I II III
A) I <II<III
B) II<III<I
C) III<II<I
D) III<I<II
Explanation
(a)
Weak base$\ \longrightarrow \$strong conjugate acid
$CH \equiv C^{-}\ \ \ \ \ \rightarrow CH \equiv CH$
weakest base (strongest acid among the given)
$CH_{3} - CH_{2}^{-}\ \ \ \ \rightarrow CH_{3}CH_{3}$
(strongest base) (weakest acid)
