The D-And-f-Block Elements

Question
CBSEENCH12011483
Wired Faculty App

The shape of gaseous SnCl2 is

  • Tetrahedral

  • Linear

  • Angular

  • T-shape

Solution

C.

Angular

Total no. of valence electron for Sn = 4
Total no. of valence electron for Cl = 7
Thus total number of valence electron for SnCl2 = 4 + 7 x 2 = 18
Bond pair = 2
Number of electrons used to complete the octets and duet = 8 x 2 = 16
No. of lone pair = 1

SnCl2 has sp2 hybridisation with one lone pair of electrons. Thus has angular shape.
