STANDARD Chemistry Reaction Mechanisms MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following products does not match correctly with the reaction?
A
CH₃CH = C(CH₃)₂ + HBr → CH₃—CH₂—C—Br
B
CH₂—CH—CH₂CH₃ + NaOH → CH₂—CH—CH₂CH₃ + NaBr + H₂O
C
(CH₃)₃CBr + KOH → CH₃—C≡CH₂ + H₂O + KBr
D
CH₃CH₂CH = CH₂ + HBr → CH₃CH₂CH₂CH₂Br
Correct Answer
Option B
Detailed Explanation
Option B shows an incorrect reaction. The reaction of an alkene with NaOH does not proceed as shown. Instead, the alkene would undergo addition reactions with HBr or other electrophiles.
