What is a double bond? A. Two covalent bonds between adjacent atoms in a molecule B. A total of two covalent bonds between molecules C. A total of two covalent bonds in a molecule D. Two covalent bonds between adjacent molecules (Please answer quickly. Thank you in advance.)

Answer 1

A double bond, would basically be a covalent bond, polar or not, between 2 atoms in a given molecule, not connecting 2 molecules together, although the later is also a covalent bond. Yet the definition of it is the first one.
