Question

Which of the following is not correct?
(i) There can be more than one sigma bond between two atoms.
(ii) Two p orbitals always overlap laterally.
(iii) A sigma bond has no free rotation around its axis.
A. (i), (ii)
B. (ii), (iii)
C. (i), (iii)
D. (i), (ii), (iii)

Answer 1

Correct Answer - D
There is always one sigma bond in multiple bonds between atoms. Two p orbitals can have axial overlap to form a sigma bond. A sigma bond has practically free rotation around its axis.
