Question

Which of the following statements is/are not true for a bond?
1. It is formed by the overlapping of p-p or p-d orbitals
2. It is stronger than sigma bond
3. It is formed when - bond exist already
4. It is resulted from axial overlapping of orbitals
(1) 1, 2, 3, 4
(2) 2,3,4
(3) 2,4
(4) 1, 2, 4​

Answer 1

Answer:

The correct option is (3) 2,4.

Because,

(2) says that pi bond is stronger than sigma bond, however it is actually the opposite, as the pi bonds are formed after sigma bonds overlap and overlapping makes sigma bonds stronger.

(4) says that pi bonds result from axial overlapping, however, they are formed by side ways overlapping, which is also why they are less strong.
