Question

An isomer of C₆H₁₂ on reaction with Br₂/ light gave only one isomer C₆H₁₁Br (X). Reaction of X with AgNO₃ gave Y as the major product. What is Y?

• A.
• B.
• C.
• D.

Hint:

When a halide like Br is substituted with NO₂ in the presence of AgNO₃, the reaction leads to the formation of a nitro group, which is commonly observed in aromatic electrophilic substitution reactions.

Answer 1

The Correct Option is D

- The isomer of C₆H₁₂ reacts with Br₂ under light, resulting in the formation of C₆H₁₁Br (X). This indicates the formation of a bromine-substituted product in the presence of Br₂ and light, indicating a free-radical substitution.
- The reaction of C₆H₁₁Br (X) with AgNO₃ typically leads to the substitution of the bromine atom with a nitro group (NO₂) when NO₃⁻ ions are involved.
- Therefore, the major product Y is NO₂, and the correct answer is NO₂.
