Solution
Chemistry ma’am · 3 steps
Find the carbon holding Cl, then check its neighbour: a C=C, a benzene ring, or neither.
- Where Cl sits. In a vinyl halide, Cl is on an sp² carbon of the C=C itself. In an allyl halide, Cl is on the sp³ carbon next to a C=C. In a benzyl halide, Cl is on the sp³ carbon next to a benzene ring. An alkyl halide has no double bond or ring nearby.
- Read structure IV. The figure is C₆H₅-CH(Cl)-CH₃. The Cl is on an sp³ carbon joined directly to the ring, so it is benzylic. Being a secondary carbon does not change that.
Example Carbon carrying Cl Type I. CH₂=CH-CH₂Cl sp³, next to C=C allyl (D) II. CH₃-CH(Cl)-CH₃ sp³, no C=C or ring alkyl (C) III. CH₂=CHCl sp², part of C=C vinyl (A) IV. C₆H₅-CH(Cl)-CH₃ sp³, next to benzene ring benzyl (B) - So. The match is A-III, B-IV, C-II, D-I, which is option (c).
The idea to keep. Vinyl and aryl: Cl is on the sp² carbon itself. Allyl and benzyl: Cl is on the sp³ carbon next to the C=C or ring. Alkyl: no π system nearby.
