Chemistry Question on Chemical bonding and molecular structure
Which of the following does not depend on the attraction of the bonding pair towards the nucleus.
A
The no. of protons in the nucleus
B
The repulsion by the electrons in the same volence shell
C
The amount of sheieding by inner shell electron
D
The distance from the nucleus
Answer
The repulsion by the electrons in the same volence shell
Explanation
Solution
The repulsion by the electrons in the same valence shell does not depend on the attraction of the bonding pair towards the nucleus. This is because electrons are identical in charge.
The repulsion can be minimised, if two electrons move as far apart as possible by occupying different degenerate orbitals or if they have parallel spins.
