Question

The correct dot formulation for nitrogen trichloride has:

• A. 2 $N-Cl$ bonds, 1 $N=Cl$ bond and 8 lone pairs of electrons.
• B. 3 $N-Cl$ bonds and 10 lone pairs of electrons.
• C. 1 $N-Cl$ bond, 2 $N=Cl$ bonds and 7 lone pairs of electrons.
• D. 3 $N=Cl$ bonds and 6 lone pairs of electrons.

Answer 1

The correct option is B 3 $N-Cl$ bonds and 10 lone pairs of electrons.

The correct dot formulation for nitrogen trichloride has 3 $N-Cl$ bonds and 10 lone pairs of electrons. Out of 10 lone pairs of electrons, one is present on $N$ atom and each $Cl$ atom has 3 lone pairs of electrons.
