JEE Main 2026 — 23 January, Evening Shift — Question 52

Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II :

Statement I: (CH3)3C⊕\left(\mathrm{CH}_{3}\right)_{3} \stackrel{\oplus}{\mathrm{C}} is more stable than C⊕H3\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{3} as nine hyperconjugation interactions are possible in (CH3)3C⊕\left(\mathrm{CH}_{3}\right)_{3} \stackrel{\oplus}{\mathrm{C}}.

Statement II: C⊕H3\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{3} is less stable than (CH3)3C⊕\left(\mathrm{CH}_{3}\right)_{3} \stackrel{\oplus}{\mathrm{C}} as only three hyperconjugation interactions are possible in C⊕H3\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{3}.

In the light of the above statements, choose the correct answer from the options given below.

  1. Option A:

    Statement I is true but Statement II is false

  2. Option B:

    Both Statement I and Statement II are true

    Correct
  3. Option C:

    Both Statement I and Statement II are false

  4. Option D:

    Statement I is false but Statement II is true

Answer: B

Step-by-step solution

S-1: (CH3)3C+>C+H3\left(\mathrm{CH}_{3}\right)_{3} \mathrm{C}^{+}>\stackrel{+}{\mathrm{C}} \mathrm{H}_{3}; due to hyperconjugation interaction S-2 : False
