Question

A molecule $AB _{2}$ contains two $\sigma,$ two $\pi$ bonds and one lone pair of electrons surrounding $A.$ The arrangement of electron pairs and Hybridisation state of central atom are, respectively

• A. Square pyramidal, $sp ^{2}$
• B. Trigonal planar, $sp ^{2}$
• C. Linear, $sp$
• D. Can't be predicted

Answer 1

Answer: (B)

Arrangement of electron pairs $\rightarrow$ Trigonal planar hybridisation of $A \rightarrow sp ^{2}$
