Single bonds involve the sharing of one pair of valence electrons between two atoms. They are typically formed between nonmetals such as hydrogen, carbon, and oxygen. In Lewis structures, single bonds are denoted by a single line (e.g., H-H or C-H). Single bonds allow for free rotation around the bond axis due to their sigma ($\sigma$) bond nature.
