The arrangement of following compounds : i. bromomethane ii. bromofonn iii. chloromethane iv. dibromomethane In the increasing order of their boiling point is

Options

  1. Aiii ( < i < i v < i )
  2. Biv ( < iii < i < i )
  3. C( ii < iii < i < iv )
  4. D( i < ii < iii < iv )

Correct answer

A. iii ( < i < i v < i )

Step-by-step solution

The intermolecular forces of attraction become stronger with the increase in size of the molecules. Hence, the order of boiling points will be ( CH ₃ Cl < CH ₃ Br < CH ₃ Br ₂ < CH Br ₃ )
