Which of the following is correct for P₄ molecule of white phosphorus? 

(i) It has 6 lone pairs of electrons. 

(ii) It has six P–P single bonds. 

(iii) It has three P–P single bonds. 

(iv) It has four lone pairs of electrons.

This is a multiple choice answer as classified in NCERT Exemplar

Correct option is (ii) and (iv)

Tetrahedral geometry characterises the structure of a white phosphorus molecule.

Phosphorus has a valency of 5, and there are four phosphorus atoms in total. As a result, there will be a total of 4×5=20 valence electrons.

As a result, each P atom will have one lone pair of electrons, and each covalent bond (two electrons) will be established.

In a molecule of white phosphorus, there will be four lone pairs of electrons and six P-P single bonds in total.
