Which formula represents the binary molecular compound phosphorus trichloride? pcl p3cl p3cl3 pcl3

Explanation:

Phosphorus trichloride is a covalent compound because sharing of electrons takes place between phosphorous and chlorine. Both the elements are non-metals and hence, will form covalent bond.

The nomenclature of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

So, the molecular formula for phosphorus trichloride is
