A) \[PC{{l}_{3}}\]
B) \[S{{O}_{3}}\]
C) \[CO_{3}^{2-}\]
D) \[NO_{3}^{-}\]
Correct Answer: A
Solution :
Key Idea: (i) Find the hybridisation of the molecule by using following formula: \[H=\frac{1}{2}(V+X-C+A)\] where, H = hybridisation V = number of electrons in valence shell of central atom X = number of monovalent atoms C = charge on cation A = charge on onion (ii) Shape is determined by knowing hybridisation and lone pair of electrons in valence shell of central atom.You need to login to perform this action.
