Options

A. `H-O-underset(H)underset(|)underset(O)underset(|)overset(O)overset(uarr)(P)-O-H`
B. `Olarrunderset(H)underset(|)underset(O)underset(|)overset(H)overset(|)(P)-O-H`
C. `Olarr underset(H) underset(|) overset(H) overset(|)P-O-H`
D. `H-O-overset(O)overset(|)P=O`

Answer

A

Explanation

Orthophosphoric acid `(H_(3)PO_(4))` is a tribasic acid . Hence , its structure can be represented as ` O larr P(OH)_(3)`. `{:(H-O-underset(H)underset(|)underset(O)underset(|)overset(O)overset(uarr)(P)-O-H),((lp+sigmabp=1+3=4)):}`
Hence , hybridisation of P in `H_3PO_4` is `sp^(3)` and thus , it is tetrahedral in shape .
