Since a carbon atom has 4 valence electrons, it can complete its valence shell by forming a total of 4 hydrogen bonds.

Question

Quizplus · Accepted Answer

Carbon can form four covalent bonds by sharing its four valence electrons with other atoms (such as hydrogen) to complete its valence shell, but these are not classified as hydrogen bonds. Hydrogen bonds are a type of weak interaction between a hydrogen atom in one molecule and an electronegative atom in another molecule, not the covalent bonding carbon engages in to complete its valence shell.
