Question

Which of the following species has tetrahedral geometry?

• A. $B{H}_4^{-}$
• B. $N{H}_2^{-}$
• C. $C{O}_3^{2-}$
• D. $H_3{O}^{+}$

Answer 1

Answer: (A)

The geometry of $B{H}_4^{-}$ is tetrahedral. $N{H}_2$ has $V$-shape, $C{O}_3^{2-}$ has trigonal planar and $H_3{O}^{+}$ has pyramidal shape.
