Practice question
Question
Among the following, the number of molecules possessing one or more lone pairs on the central atom is ________________ (in integer). BeCl ₂ SnCl ₂ BF ₃ NH ₃ SF ₄ PF ₅ and SF ₆ (NAT)
Explanation
In chemistry, molecular bonding dictates that hybridization and orbital overlap dictate geometry and reactivity. Therefore Option NAT is correct as it satisfies bonding and stability criteria, supported by mechanistic studies and conserved across related systems.
