The option(s) in which at least three molecules follow Octet Rule is(are)
The option(s) in which at least three molecules follow Octet Rule is(are)
Updated On: Mar 7, 2025
- CO2, C2H4, NO and HCl
- NO2, O3, HCl and H2SO4
- BCl3, NO, NO2 and H2SO4
- CO2, BCl3, O3 and C2H4
Hide Solution
Verified By Collegedunia
The Correct Option is A, D
Solution and Explanation
Step 1: Understanding the Octet Rule
The octet rule states that atoms tend to form bonds to achieve a stable electron configuration of eight valence electrons.
Step 2: Analyzing Each Option
- (A) The molecules CO₂, C₂H₄, and HCl obey the octet rule, but NO has an odd number of electrons, making it an exception.
- (B) The molecules NO₂ and O₃ do not strictly follow the octet rule due to resonance and unpaired electrons.
- (C) BCl₃ does not obey the octet rule as boron has an incomplete octet, and NO₂ also deviates due to its odd electron count.
- (D) The molecules CO₂, BCl₃, O₃, and C₂H₄ are analyzed, and at least three among them follow the octet rule.
Conclusion:
Based on the analysis, the correct option is identified.
