Chapter U2.5, Problem 2E

Interpretation Introduction

Interpretation :

The octet rule needs to be explained. The use of it to make molecular structure needs to be explained.

Concept Introduction :

Octet rule states that while forming bonds all the participating atoms try to attain eight electrons in the valence shell similar to inert gases.

Answer to Problem 2E

Eight electrons in the valence shell is a characteristic of noble gases. All the atoms during bond formation prefer to attain this eight electrons. This is octet rule. Following octet rule, molecular structures for different molecules can be created.

Explanation of Solution

Octet rule is very important which helps to draw structures of different compounds.

Maximum atoms which are participating in bond formation try to keep total four bonds or eight electrons in the valence shell. For example, methane molecule has a central carbon atoms which is bonded to four hydrogen and thus it has attained octet.
