Which among the following statements is true for haloalkyne?
Show Hint
Alkane $\to sp^3$; Alkene $\to sp^2$; Alkyne $\to sp$.
Updated On: Apr 26, 2026
- Halogen atom is bonded to 'sp' hybridised carbon atom.
- Halogen atom is bonded to ' sp$^2$, hybridised carbon atom of aliphatic chain.
- Halogen atom is bonded to ' sp$^3$, hybridised carbon atom next to a carbon-carbon double bond.
- Halogen atom is bonded to ' sp$^2$ ' hybridised carbon atom of aromatic ring.

The Correct Option is A
Solution and Explanation
Step 1: Concept
Haloalkynes are organic compounds where a halogen atom is directly attached to a carbon atom involved in a triple bond ($C \equiv C$).
Step 2: Analysis
In an alkyne, the carbon atoms involved in the triple bond are $sp$ hybridized. Therefore, in a haloalkyne, the halogen is bonded to an $sp$ carbon.
Step 3: Comparison
- Option (B) describes haloalkenes (vinylic). - Option (C) describes allylic halides. - Option (D) describes haloarenes (aryl halides).
Final Answer: (A)
