What is a 2 degree carbocation?

A 2-degree (or secondary) carbocation is a positively charged carbon atom that is bonded to two other carbon atoms and one hydrogen atom. It is formed when a carbon atom loses a bonding electron, resulting in a stable structure typically found in organic reactions. Secondary carbocations are less stable than tertiary carbocations but more stable than primary carbocations due to the inductive effect and hyperconjugation from neighboring carbon atoms. They often participate in reactions such as alkylation and rearrangement.
