Each carbon atom would share one pair of electrons with hydrogen and one pair with the other carbon atom.

Answer 1

In acetylene (C2H2), each carbon atom forms:

• A triple bond with the other carbon atom, which consists of three pairs of shared electrons.
• A single bond with one hydrogen atom, which consists of one pair of shared electrons.

Thus, the correct description of how each carbon atom in acetylene bonds is:

Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.
