Question

The p-p-p angle in white phosphorous is
(a) 120°
(b) 109° 28'
(c) 90°
(d) 60°

Answer 1

The p-p-p angle in white phosphorous is
(a) 120°
(b) 109° 28'
(c) 90°
(d) 60°

Ans. 60°.

The molecular formula of white phosphorous is P4. In this structure four phosphorus atoms lie at the corners of the regular tetrahedron. Each of phosphorous atom is linked to other three phosphorous atoms by covalent bonds. The P-P bond length is 2.21 A and PPP angle is 60 degrees.

No. of P-P-P bonds in P4 (white Phosphorus) molecule is 4.
