Arrange the following elements in increasing order of their electronegativity.

1. Carbon, Nitrogen, Silicon, Phosphorus
2. Nitrogen, Silicon, Carbon, Phosphorus
3. Silicon, Phosphorus, Carbon, Nitrogen
4. Phosphorus, Silicon, Nitrogen, Carbon

Correct answer: Silicon, Phosphorus, Carbon, Nitrogen

Solution

The electronegativity order is Si < P < C < N based on the positions of the elements in the periodic table and the trends in electronegativity.
