The given compound C₆H₅-CH=CH-CH(X)-CH₂CH₃ (benzene ring attached to CH=CH-CH(X)-CH ₂ CH ₃ ) is an example of ________. 1. vinylic halide 2. benzylic halide 3. aryl halide 4. allylic halide

Answer: 4. allylic halide Key idea: A halide is named by the carbon that carries the halogen. In C₆H₅-CH=CH-CH(X)-CH₂CH₃ , X is on an sp³ carbon next to a C=C double bond. A halogen on an sp³ carbon adjacent to a C=C is an allylic halide. Vinylic: X directly on a C=C carbon. Benzylic: X on an sp³ carbon directly attached to the benzene ring. Here the carbon next to the ring is =CH, so no. Aryl: X directly on the ring.

Best answer

Answer: 4. allylic halide

Key idea: A halide is named by the carbon that carries the halogen.

In \(\mathrm{C_6H_5-CH=CH-CH(X)-CH_2CH_3}\), X is on an \(sp^3\) carbon next to a C=C double bond. A halogen on an \(sp^3\) carbon adjacent to a C=C is an allylic halide.

Vinylic: X directly on a C=C carbon.
Benzylic: X on an \(sp^3\) carbon directly attached to the benzene ring. Here the carbon next to the ring is =CH, so no.
Aryl: X directly on the ring.
