STANDARD Chemistry Elimination and Ozonolysis MCQ Question

Type: MCQ-conceptual-Medium-Class 11

The products for the following reactions are (i) CH₃−C−CH₂−CH₃ + alc. KOH → X (ii) CH₃−CH=CH−CH₂ + O₃ → Y + X

A

X = (CH₃)₂C=CH₂, Y = CH₃CH₂CHO, Z = CH₃CH₂CHO

B

X = CH₂=CH₂, Y = CH₃CHO, Z = CH₃COOH

C

Image of a chemical structure

D

X = CH₃−CH=C(CH₃)₂, Y = HCHO, Z = CH₃CHO

Correct Answer

Option D

Detailed Explanation

In reaction (i), the elimination of HBr from the alkyl halide using alcoholic KOH results in the formation of 2-butene (X). In reaction (ii), ozonolysis of 2-butene gives formaldehyde (HCHO) and acetaldehyde (CH₃CHO) as products.
