Q24. Match List-I with List-II:
List-I
(A) CH3CH2Br + alc. KOH →
(B) CH3CH2Br + aq. KOH →
(C) CH3CH2

Q: What is the correct answer for CUET UG Chemistry Q24?

The correct answer is c. (A) CH₃CH₂Br + alcoholic KOH: Undergoes elimination (dehydrohalogenation) to form an alkene, CH₂=CH₂ (II).(B) CH₃CH₂Br + aqueous KOH: Undergoes nucleophilic substitution (SN2) to form an alcohol, CH₃CH₂OH (IV).(C) CH₃CH₂Br + KNO₂: KNO₂ is an ambident nucleophile. It attacks primarily through the oxygen atom, forming an alkyl nitrite, CH₃CH₂ONO (III).(D) CH₃CH₂Br + AgNO₂: AgNO₂ is also an ambident

FirstInTest · Accepted Answer

(A) CH₃CH₂Br + alcoholic KOH: Undergoes elimination (dehydrohalogenation) to form an alkene, CH₂=CH₂ (II).(B) CH₃CH₂Br + aqueous KOH: Undergoes nucleophilic substitution (SN2) to form an alcohol, CH₃CH₂OH (IV).(C) CH₃CH₂Br + KNO₂: KNO₂ is an ambident nucleophile. It attacks primarily through the oxygen atom, forming an alkyl nitrite, CH₃CH₂ONO (III).(D) CH₃CH₂Br + AgNO₂: AgNO₂ is also an ambident nucleophile. It attacks primarily through the nitrogen atom, forming a nitroalkane, CH₃CH₂NO₂ (I).Thus, the correct matching is (A)-(II), (B)-(IV), (C)-(III), (D)-(I).

Answer
