Lewis Structure

A diagrammatic representation of the bonding between atoms of a molecule and the lone pairs of electrons in the molecule.

Ethyne

Also known as acetylene, it is a colorless gas used as a fuel and a chemical building block.

Double Bonds

Chemical bonds formed when two pairs of electrons are shared between two atoms, resulting in stronger attraction and shorter bond length compared to single bonds.
