Question

Identify 'B' in the following reaction.

\[\ce{2-Bromobutane ->[KOH alc.][\Delta] A ->[HI] B}\]

पर्याय

• But-1-ene

• 2-Iodobutane

• 1-Iodobutane

• Butan-2-ol

Answer 1

2-Iodobutane

Explanation:

\[\begin{array}{cc}
\ce{H3C - CH - CH2CH3 ->[alc.][\underset{\Delta}{KOH}] \underset{But-2-ene}{H3C - CH = CH - CH3} ->[HI] H3C - CH - CH2 - CH3}\\
\phantom{}|\phantom{........................................................}|\phantom{.........}\\
\phantom{}\ce{\underset{2-Bromobutane}{Br}}\phantom{..............................................}\ce{\underset{2-Iodobutane}{I}}\phantom{.........}
\end{array}\]
