In the vapor phase, formic acid exists as dimers (complexes consisting of two formic acid molecules) rather than individual molecules. The formic acid dimer is held together by two hydrogen bonds.
Which of the following diagrams correctly represents the hydrogen bonding (denoted by dotted lines) in the formic acid dimer?
