The major product \(C\) in the below mentioned reaction is :
\(C{H}_{3}C{H}_{2}C{H}_{2}Br\overset{Alc.KOH}{\underset{\Delta }{\to }}A\overset{HBr}{\to }B\overset{\text{Aq }KOH}{\underset{∆}{\to }}C\)
[Re-NEET 2024]
Propan-2-ol
-
CH₃CH₂CH₂Br + alc. KOH (∆) → propene (elimination)
-
propene + HBr → 2‐bromopropane (Markovnikov addition)
-
2‐bromopropane + aq. KOH → 2‐propanol (nucleophilic substitution).
The major product \(C\) in the below mentioned reaction is :
\(C{H}_{3}C{H}_{2}C{H}_{2}Br\overset{Alc.KOH}{\underset{\Delta }{\to }}A\overset{HBr}{\to }B\overset{\text{Aq }KOH}{\underset{∆}{\to }}C\)
