Given below are two statements: Statement I: Neopentane forms only one monosubstituted derivative. Statement II: Melting point of neopentane is higher than n-pentane. In the light of the above statements, choose the most appropriate answer from the options given below: (1) Statement I is incorrect but Statement II is correct (2) Both Statement I and Statement II are incorrect (3) Both Statement I and Statement II are correct (4) Statement I is correct but Statement II is incorrect

  1. Statement I is incorrect but Statement II is correct
  2. Both Statement I and Statement II are incorrect
  3. Both Statement I and Statement II are correct
  4. Statement I is correct but Statement II is incorrect

Correct answer: Both Statement I and Statement II are correct

Solution

Statement I is correct because neopentane has a symmetrical structure that allows for only one unique monosubstituted derivative. Statement II is also correct as neopentane has a higher melting point than n-pentane due to its compact structure, which leads to stronger van der Waals forces.
