Question

Which one of the following does not follow octate rule? (A) PF3 (B) BF3 (C) CO2 (D) CCl4

Tardigrade Admin · Accepted Answer

BF 3 does not follow octet rule because central boron atom is surrounded by 6 electrons. 3 electrons are of B atom and remaining 3 electrons are of 3 F atoms. To satisfy octet rule, 8 electrons are required. Boron lacks an electron pair. Hence, it also acts as Lewis acid

$P F_{3}$

$B F_{3}$

$C O_{2}$
