Question

Write the chemical formula for the covalent compound nitrogen trichloride and mention their molecular weight in brackets after the formula.

Answer 1

Nitrogen trichloride:

• Nitrogen trichloride is a covalent compound that exists as a yellow oily liquid having molecular formula ${\mathbf{NCl}}_{\mathbf{3}}$.
• It is also known as trichloramine. It explodes very easily and is immiscible.
• It is composed of one nitrogen atom and three chlorine atoms.

Molecular weight of Nitrogen trichloride: = Mass of Nitrogen atom + 3(Mass of chlorine atom)

Molecular weight of Nitrogen trichloride: = (14 + 3(35.5)) = 120.359 g mol^-1

Thus, the chemical formula and molecular weight of nitrogen trichloride is ${\mathbf{NCl}}_{\mathbf{3}}$(120.359 g mol^-1 ).
