Multiple choice

Assertion: A triplet carbene is more stable than a singlet carbene. Reason: In triplet carbene, carbon atom is sp-hybridized while in singlet carbene it is sp2-hybridized.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are true but R is NOT the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

  5. Both A and R are false.
