Final answer:
The Lewis structure of HCN (H bonded to C) does not have nonbonding electron pairs.
Step-by-step explanation:
The correct answer is B) Incorrect, it does not have nonbonding electron pairs.
The Lewis structure of HCN (H bonded to C) only shows the bonding electron pairs, which are the electrons involved in the covalent bonds between the atoms. The lone pairs or nonbonding electron pairs are not shown in the Lewis structure.
In the Lewis structure of HCN, the carbon atom forms a triple bond with the nitrogen atom and a single bond with the hydrogen atom. The nitrogen atom has a lone pair of electrons, which is not involved in bonding and is represented as a pair of dots.
