WebDouble-stranded DNA has a regular geometric structure with a fixed distance between the two backbones. This requires the bases pairs to consists of one base with a two-ring (bicyclic) structure (these bases are called purines) and one with a single ring structure (these bases are called pyrimidines). WebSo this is the most stable conjugate base out of these three. Therefore, this is the most acidic compound out of these three. The inductive effect falls off over distance.
