Question

The geometry of $${H_2}S$$  and its dipole moment are

A. angular and non-zero  
B. angular and zero
C. linear and non-zero
D. linear and zero
Answer :   angular and non-zero
Solution :
Hybridisation of $$S\,\,in\,\,{H_2}S = \frac{1}{2}\left( {6 + 2 + 0 - 0} \right) = 4$$
∴ $$S$$   has $$s{p^3}$$  hybridisation and $$2$$  lone pair of electrons in $${H_2}S$$
∴ It has angular geometry and so it has non-zero value of dipole moment.
