Question

Which of the following has smallest bond angle? (A) Ethane (B) Ethene (C) Ethyne (D) Ethanol

Tardigrade Admin · Accepted Answer

The bond length of Ethane C-C is 1.54 sp3-sp3 Ethene C=C is 1.34 sp2-sp2 Ethyne C≡ C is 1.20 sp-sp Ethanol C-O is 1.42 sp3-sp So, the smallest bond angle is of ethyne.

Q. Which of the following has smallest bond angle?

Ethane

Ethene

Ethyne

Ethanol

The bond length of
Ethane $C - C$ is $1.54 s p^{3} - s p^{3}$
Ethene $C = C$ is $1.34 s p^{2} - s p^{2}$
Ethyne $C \equiv C$ is $1.20 s p - s p$
Ethanol $C - O$ is $1.42 s p^{3} - s p$
So, the smallest bond angle is of ethyne.
