Given below are two statements: Statement I: Propene on treatment with diborane gives an addition product with the formula $\left(\left(\mathrm{CH}_3\right)_2-\mathrm{CH}_{)_3} \mathrm{~B}\right.$. Statement II: Oxidation of $\left(\left(\mathrm{CH}_3\right)_2-\mathrm{CH}\right)_3 \mathrm{~B}$ with hydrogen peroxide in presence of NaOH gives propan-2ol. In the light of the above statements, choose the most appropriate answer from the options given below:

• A

  Statement I is correct but Statement II is incorrect
• Correct answer
  B

  Statement I is incorrect but Statement II is correct
• C

  Both Statement I and Statement II are correct
• D

  Both Statement I and Statement II are incorrect

Solution

$\mathrm{CH}_3 \mathrm{CH}=\mathrm{CH}_2+\left(\mathrm{H}-\mathrm{BH}_2\right)_2 \longrightarrow \mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{BH}_2 \xrightarrow{\mathrm{CH}_3 \mathrm{CH}-\mathrm{CH}_2}\left(\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2\right)_2 \mathrm{BH}$

Statement I is incorrect but Statement II is correct.

Hence, the correct answer is option: 'B'.
