Question

The state of hybridization of the central atom is not the same as in the others :
(a) B in BF,
(b) O in H2O
(c) N in NH3
(d) P in PCI3
​

Answer 1

Answer:

beacuse due to the presence of monovalent atoms.

Explanation:

Flourine,Hydrogen,Chlorine are monovalent atom

Answer 2

Answer:

(B)

Explanation:

B IN BF3 HAS 3 SIGMA ONE LONE PAIR SO ITS HYB- SP3

ALSO N AND P IN NH3 AND PCl3 have 3 sigma and one lone pair so they are also sp3

but, in H2O, O has 2 sigma and 1 lone pair so it is sp2 hybridised
