NEET levelSingle correct optionDifficulty 1 of 3g3173

The kinetic product of a reaction in which two products can form from the same reactant is the product that

  1. Ais lower in energy (more stable)
  2. Bis formed more slowly but is more stable
  3. Cis formed faster, through the transition state of lower energy
  4. Dis formed only at high temperature

Answer: C

Kinetic control means the product ratio is set by relative rates. The product formed faster has the lower activation energy, and it need not be the more stable one.
