Question

Two statements are given below: 
Statement I: Octet theory accounts for the shape of the molecules. 
Statement II: Octet theory does not explain the relative stability of the molecules. 
The correct answer is: 
 

• A. Both statement-I and statement-II are correct
• B. Both statement-I and statement-II are not correct
• C. Statement-I is correct but statement-II is not correct
• D. Statement-I is not correct but statement-II is correct

Hint:

The octet theory is useful for understanding the electron configuration of atoms but has limitations in explaining molecular shapes and stability.

Answer 1

The Correct Option is D

- Statement I: The octet theory primarily explains the tendency of atoms to have eight electrons in their valence shell to achieve stability. It does not directly account for the shape of molecules, which is better explained by the VSEPR (Valence Shell Electron Pair Repulsion) theory. Therefore, Statement I is not correct. 
- Statement II: The octet theory does not explain the relative stability of molecules, especially in cases where molecules have expanded octets or odd-electron species. 
Thus, Statement II is correct. 
Final Answer: Statement-I is not correct but statement-II is correct
