What does “Octet rule” actually mean in Chemical Bonding & Molecular Structure, and why does it matter for JEE?
atoms tend to gain, lose or share electrons to reach eight in their outer shell.
In simple words: atoms tend to gain, lose or share electrons to reach eight in their outer shell. Getting Octet rule clear matters because JEE questions on Chemical Bonding & Molecular Structure usually test this idea directly, not just a formula you memorised.
Key point
Octet rule
Common mistake
forcing an octet on exceptions like BeCl₂, BF₃ or SF₆.
Memory tip
the octet rule is a guide, not a law — watch for electron-deficient and expanded-octet molecules.
