Which of the following is the most stable carbocation:
Correct answer: C. Teritary
- A. Secondary
- B. Primary
- C. Teritary
- D. All have same stability
Explanation
Order of stability of carbocations: Tertiary>Secondary>Primary Stability of R+ ∞ Number of β-hydrogens ∞ Inductive effect The correct option is C) Tertiary Carbocation. Tertiary carbocations are the most stable among the options provided. This is because the presence of three alkyl groups (R3) around the positively charged carbon atom in a tertiary carbocation provides more electron-donating groups, stabilizing the positive charge through inductive and hyperconjugation effects. This increased stability makes tertiary carbocations less prone to rearrangement or reaction with nucleophiles compared to secondary or primary carbocations.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
