“Stability of carbocation depends upon the electron releasing inductive effect of groups adjacent to positively charged carbon atom involvement of neighbouring groups in hyper-conjugation and resonance.”
The structure of triphenylmethylcation is given below. This is very stable and some of its salts can be stored for months. Explain the cause of high stability of this cation.

The triphenylmethylcation is very stable because, it is a tertiary carbocation as well as the positive charge present on the carbon atom is being stabilised by three phenyl groups via resonance.

As we know that the phenomenon of resonance, leads to enormous stability of carbocation, as there is delocalisation of electron cloud, and the phenyl ring has great amount of delocalised electrons which are very potentially stabilising the positive charge lying on the carbon.
