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.
