An **allylic halide** has the halogen bonded to:
AA carbon directly part of C=C double bond
BA sp³ carbon adjacent to (next to) a C=C double bond
CAn aromatic carbon
DA sp carbon
Answer & Solution
Correct answer: B. A sp³ carbon adjacent to (next to) a C=C double bond
Allylic position = the sp³ carbon NEXT to a double bond. Example: CH₂=CH-CH₂-X. Different from vinyl halides where X is ON the double-bond carbon (CH₂=CH-X).
