The question below replied by you does not explain how the hybridization has been arrived. Q. 3. In which of the following the central atom does not use sp3 hybrid orbitals in its bonding? (a) BeF3- (b) OH3+ (c) NH2- (d) CH3CH2CH2OH In Chemistry Asked by: VENIKA SINGHAL, on Sep 04, 2011 Ans. In BeF3- the central atom does not use sp3 hybrid orbitals in its bonding.Instead the central atom Be is sp2 hybridised

Expert Answer:

The electronic configuration of Be is 1s2 2s2.
One electron is promoted from 2s orbital to 2p orbital.So the electronic configuration become is 1s2 2s12p1.
Now, Be combine with 3 F atoms using its one s and two p-orbital to form sp2 hybridisation.
