Which of the following carbocation is most stable?
Correct answer: B. (CH3)3C
- A. (CH3)3C-CH2
- B. (CH3)3C
- C. CH3CH2CH2
- D. CH3CH CH2CH3
Explanation
The most stable carbocation is the one that has the most alkyl groups attached to it. In this case, option B, (CH3)3C, is the most stable because it is a tertiary (3°) carbocation with three methyl (CH3) groups attached. Tertiary carbocations are more stable than secondary or primary ones due to the electron-donating nature of alkyl groups. Therefore, option b is correct.

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.

In elimination reaction there is another site present in the alkyl halide molecule where the attacking reagent (base) can attack at the same time. Such a site is an electrophilic hydrogen atom (β-hydrogen is acidic in nature) which is attached to the β-carbon of the alkyl halide. When the attack takes place on hydrogen we get an alkene there are two types of elimination reactions (E1 and E2): Which of the following statements is incorrect about E2 elimination reaction?
