Given below are two statements: Statement I : ( CH ₃ )₃ C is more stable than C H ₃ as nine hyperconjugation interactions are possible in ( CH ₃ )₃ C . Statement II : C H ₃ is less stable than ( CH ₃ )₃ C as only three hyperconjugation interactions are possible in C H ₃ . In the light of the above statements, choose the correct answer from the options given below

Options

  1. AStatement I is false but Statement II is true
  2. BStatement I is true but Statement II is false
  3. CBoth Statement I and Statement II are true
  4. DBoth Statement I and Statement II are false

Correct answer

B. Statement I is true but Statement II is false

Step-by-step solution

Statement I: In the tert-butyl carbocation (CH₃)₃C^+ , there are three methyl groups attached to the carbocationic carbon. Each methyl group has 3 -hydrogens, making a total of 9 -hydrogens. Thus, 9 hyperconjugation interactions are possible, which significantly stabilize the carbocation. Statement I is true. Statement II: In the methyl carbocation CH₃^+ , there are no -carbons and consequently no -hydrogens. Hyperconjugation requires the presence of at least one -hydrogen on a carbon adjacent to the sp^2 hybridize
