The hybridisation of the central atom will change when
Options
- AN H 3 combines with H +
- BH 3 B O 3 combines with O H -
- CN H 3 forms N H 2 -
- DH 2 O combines with H +
Correct answer
B. H 3 B O 3 combines with O H -
Step-by-step solution
Here hybridisation changes from s p 2 to s p 3 when H 3 B O 3 combines with O H - H 3 B O 3 s p 2 + O H - → [ B ( O H ) 4 ] - s p 3 In rest other reactions hybridisation does not change N . . H 3 s p 3 + H + → N H 4 + s p 3 2 N H 3 s p 3 ⇌ 2 N H 2 - s p 3 + N H 4 + s p 3 H 2 O s p 3 + H + ⇌ H 3 O + s p 3
