Definitions:

Nitrogens

Chemical elements with the symbol N and atomic number 7, essential for all living organisms.

Pi Bonds

Covalent chemical bonds formed by the side-to-side overlap of p orbitals, characterizing the electron density located above and below the axis of the bonded atoms.

Sigma Bonds

Single covalent bonds formed between two atoms due to the head-on overlap of atomic orbitals, characterized by shared electron density along the axis connecting the nuclei.

HNC Bond Angle
