Q16 / 90 · JEE Main 2016 (09 Apr Online) · Chemistry

Assertion: Rayon is a semisynthetic polymer whose properties are better than natural cotton.

Reason: Mechanical and aesthetic properties of cellulose can be improved by acetylation.

  • A
    Both assertion and reason are correct, but the reason is not the correct explanation for the assertion.
  • Correct answer
    B
    Both assertion and reason are correct, and the reason is the correct explanation for the assertion.
  • C
    Assertion in incorrect statement, but the reason is correct.
  • D
    Both assertion and reason are incorrect.
