Question

question 10 (1 point)
what is the shape of an alkyne molecule?
a) bent
b) linear
c) tetrahedral
d) trigonal planar
e) none of the above

Explanation:

Alkynes have a triple bond between carbon atoms. The carbon atoms involved in the triple bond are \( sp \) hybridized. \( sp \) hybridization results in a linear geometry. For example, in ethyne (\( C_2H_2 \)), the \( H - C\equiv C - H \) bond angle is \( 180^{\circ} \), which is characteristic of a linear shape.

Answer:

B. linear
