A
SF6, PCl5, BeCl2, BF3
💡 Explanation:
BeCl2: 4 electron in valence shell of Be ( incomplete octet)
BF3: 6 electrons is valence shell of B (incomplete octet)
SF6: 12 electrons in valence shell of S (expanded octet).
PCl5: 10 electrons in valence shell of P (expanded octet).
All of the above are exceptions of octet rule.
