The states of Hybridisation of boron and oxygen atoms in boric acid\[({{H}_{3}}B{{O}_{3}})\]are respectively            

A) \[s{{p}^{2}}\]and\[s{{p}^{2}}\] 

B)        \[s{{p}^{2}}\]and\[s{{p}^{3}}\] 

C)        \[s{{p}^{3}}\]and \[s{{p}^{2}}\]       

D)        \[s{{p}^{3}}\]and\[s{{p}^{3}}\]

Correct Answer: B

Solution :

Boron has three bonds thus\[s{{p}^{2}}\]hybridized. Each oxygen has two bonds and two lone pair hence\[s{{p}^{3}}\]hybridised.
