Question

if two carbon atoms are joined by a triple bond, how many other atoms can each carbon atom bond with

Answer 1

Each carbon atom in ethane forms 4 bonds: 1 to a carbon atom and 3 to each of the attached hydrogen atoms. A single covalent bond containing 2 shared electrons is also called a sigma (σ) bond. The simplest form of a σ bond is the overlap of two s orbitals.
