A- Out of five valence electrons of P atom- 3 electrons are involved in bond formation with three other P atoms and one lone pair is remaining-Thus- statement A is correct-B- White phosphorus has a pyramidal structure with a bond angle of 600-Thus- statement B is incorrect-C- A P4 molecule has six P-P bonds-Thus- statement C is correct-D- White phosphorus disproportionates on reaction with alkalis-P4-3NaOH-3H2O-x2192-3NaH2PO2sodium-xA0-hypophosphite-PH3phosphineThus- the statement D is correct-
