Multiple Choice

Which of the following statements correctly describes the Lewis dot structure of neutral N2Cl2?

Each nitrogen atom forms a single bond with the other nitrogen and two single bonds with chlorine atoms.

Both chlorine atoms are bonded directly to each other, with each also bonded to a nitrogen atom.

Each nitrogen atom forms a double bond with the other nitrogen and a single bond with one chlorine atom.

The two nitrogen atoms are connected by a triple bond, and each is bonded to one chlorine atom.

Verified step by step guidance

Recall that the Lewis dot structure represents the valence electrons of atoms and how they are shared or paired in bonds to satisfy the octet rule (or duet for hydrogen).

Determine the total number of valence electrons in N2Cl2 by adding the valence electrons of each atom: nitrogen has 5 valence electrons and chlorine has 7 valence electrons.

Consider the bonding preferences: nitrogen typically forms three bonds to complete its octet, and chlorine typically forms one bond with three lone pairs to complete its octet.

Analyze the given options by checking if the bonding pattern satisfies the octet rule for each atom and if the total number of bonds and lone pairs matches the total valence electrons.

Identify the correct Lewis structure where each nitrogen atom forms a double bond with the other nitrogen and a single bond with one chlorine atom, ensuring all atoms have complete octets and the molecule is neutral.
