Acids generally contain polar covalent bonds.

Is an acid an ionic or covalent compound?

Acids are molecular compounds that dissolve in water to produce hydrogen ions and an anion. Bases are ionic compounds consisting of hydroxide ions and a cation. The naming rules for acids are based on the suffix of the anion.

Are all acids molecular compounds?

Acids are molecular, which means that in their pure state they are individual molecules and do not adopt the extended three-dimensional structures of ionic compounds like NaCl. Since acids produce H+ cations upon dissolving in water, the H of an acid is written first in the formula of an inorganic acid.

A Lewis acid is a substance that accepts a pair of electrons to form a covalent bond. A Lewis base is a substance that donates a pair of electrons to form a covalent bond. So, a Lewis acid-base reaction is represented by the transfer of a pair of electrons from a base to an acid.
