question
in an alkyne, the bond angles surrounding the carbons participating in triple bonds are:
select the correct answer below:
90°
109.5°
120°
180°

Explanation:

In alkynes, carbons with triple - bonds are sp - hybridized. Sp - hybridized orbitals have a linear geometry, resulting in bond angles of $180^{\circ}$.

Answer:

D. $180^{\circ}$
