The correct statements from the following are: a) The total number of sigma bonds present in benzene is 12 b) LiF is more covalent than KF c) SnCl ₂ is more covalent than SnCl ₄

Options

  1. Aa, c
  2. Ba, b
  3. Cb, c
  4. Da, b, c

Correct answer

A. a, c

Step-by-step solution

- a) The total number of sigma bonds present in benzene is 12. This is correct. Benzene ( ( C ₆ H ₆ )) is a hexagonal ring with six carbon atoms. Each carbon atom is bonded to two other carbon atoms and one hydrogen atom. - There are ( 6 C - C ) sigma bonds within the ring. - There are ( 6 C )-H sigma bonds on the periphery. - Total sigma bonds (=6+6=12 ). - b) LiF is more covalent than KF. This is incorrect. According to Fajan's rules, a smaller cation and a larger anion lead to greater covalent character. Both (
