Adenine and thymine forms 2 hydrogen bonds, while guanine and cytosine forms 3 hydrogen bonds.

Adenine does not pair with guanine or cytosine because its pairing with thymine makes these 2 DNA bases stable.

Adenine does not fit very well with guanine and cytosine because they would prefer to bond with 3 hydrogen bonds.

Adenine and guanine are purines, which have two organic rings and thymine and cytosine are pyridines, which have one organic ring. In order for the nucleotides to fit only purines can pair with pyridines.
