Question

What is the correct name for the covalent compound NI₃?

a. Nitrogen Diiodide
b. Iodonitrogen
c. Nitrogen Triiodide
d. Nitrogen Iodide

Answer 1

The correct name for the covalent compound NI₃ is Nitrogen Triiodide, using the prefix 'tri-' for the three iodine atoms present.

Step-by-step explanation:

The correct name for the covalent compound NI₃ is c. Nitrogen Triiodide. In covalent compounds (also known as molecular compounds), the names are based on the number of each type of atom present in the compound. The prefix ‘tri-’ indicates that there are three iodine atoms. Thus, the proper naming convention combines the prefix 'tri-' for three iodine (I) atoms with the name of the element nitrogen (N), resulting in Nitrogen Triiodide.

Answer 2

The correct name for the covalent compound NI₃ is Nitrogen Triiodide, which follows the nomenclature rules for covalent compounds.

Step-by-step explanation:

The correct name for the covalent compound NI₃ is c. Nitrogen Triiodide. This nomenclature is based on the rules for naming covalent compounds, where the first element is named using its elemental name, and the second element is named as an anion with an 'ide' suffix. The prefixes (di-, tri-, tetra-, etc.) indicate the number of atoms of each element in the molecule. In the case of NI₃, 'nitrogen' indicates the nitrogen element, and 'triiodide' indicates the presence of three iodine atoms. Therefore, the correct answer is 'c. Nitrogen Triiodide'.
