Identify the statement which is not correct?

Options

  1. ADehydrobromination of 2-bromopentane gives pent1-ene as the major product.
  2. BFreon 12 is manufactured by Swarts reaction.
  3. CCHCl ₃ is stored in closed, dark coloured bottles.
  4. DChronic exposure to CHCl ₃ causes liver damage.

Correct answer

A. Dehydrobromination of 2-bromopentane gives pent1-ene as the major product.

Step-by-step solution
