Which of the following is the correct name for the compound hf?

Answer : The correct name of the compound is hydrogen fluoride.

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

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..

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

So, the name of the compound is hydrogen fluoride.
