STANDARD Chemistry Reactions of Alkanes MCQ Question
In the given reactions: (i) CH₃Br − Na, ether → X − Br₂, hv → Y − Na, ether → Z (ii) CH₃COOH − NaOH, CaO → X − NaOH, CaO → Y − Br₂, hv → Z Identify X, Y and Z.
X: (i) CH₄, (ii) CH₃COONa; Y: CH₃Br, CH₃CH₃; Z: CH₃CH₃, CH₃CH₂Br
X: (i) CH₃CH₃, (ii) CH₃COONa; Y: CH₄, CH₄; Z: CH₃Br, CH₃CH₂Br
X: (i) CH₄, (ii) CH₃COONa; Y: CH₃CH₃, CH₄; Z: CH₃Br, CH₃CH₂Br
X: (i) CH₃CH₃, (ii) CH₃COONa; Y: CH₃Br, CH₃CH₃; Z: CH₃CH₃, CH₃CH₂Br
Correct Answer
Detailed Explanation
In reaction (i), CH₃Br reacts with Na to form CH₄ (X), which on bromination forms CH₃Br (Y), and further reaction with Na forms CH₃CH₃ (Z). In reaction (ii), CH₃COOH reacts with NaOH to form CH₃COONa (X), which on decarboxylation forms CH₃CH₃ (Y), and bromination forms CH₃CH₂Br (Z).
