\( (CH_3)_3\;C^{+}\)is a tertiary carbocation. A tertiary carbocation is the most stable carbocation due to the electron releasing effect of three methyl groups. An increased + I effect by three methyl groups stabilizes the positive charge on the carbocation. Hyperconjugation and resonance energy is also responsible for the stability of tertiary carbocations.
