Detailed explanation-1: -Hydrogen is an exception to the octet rule. H forms only one bond because it needs only two electrons.
Detailed explanation-2: -It’s called the HONC rule, or sometimes known as HONC 1234 rule. The number refers to the number of bonds each of the element makes: Hydrogen makes 1 bond, Oxygen makes 2 bonds, Nitrogen makes 3 bonds and Carbon makes 4 bonds.
Detailed explanation-3: -A single hydrogen atom can participate in two hydrogen bonds, rather than one. This type of bonding is called “bifurcated” (split in two or “two-forked"). It can exist, for instance, in complex natural or synthetic organic molecules.
Detailed explanation-4: -To form molecular hydrogen, two H atoms need to share their outermost electrons. By sharing these electrons (1 from one H atom and 1 from another H atom), a single covalent bond is formed.
