Question

Shape and hybridisation of $SO_2$ are

• A. V shape, sp
• B. triangular planar, sp$^2$
• C. V shape, sp$^2$
• D. tetrahedral, sp$^2$

Answer 1

Answer: (C)

V shape, sp$^2$

Answer 2

In SO$_2$, the number of hybrid orbitals $\, \, \, \, \, \, \, \, \, \, \, H=\frac{1}{2}[v+M-C+A]$ $\, \, \, \, \, \, \, \, \, \, \, =\frac{1}{2}[6+0-0+0]=3$ Thus, hybridisation is $sp^2$ Since, SO$_2$ contains one lone pair of electrons, its geometry becomes V shape.
