4) one s orbital three p orbitals intermixing to gives four hybrid orbitals known as a) sp4 b) sp2 c) sp5 d) sp3 ​

Answer 1

Answer:

Option B

Option A

Option D

Option C

Answer 2

Answer:

1  option - A(sp)

2 option - A(sp3)

3 option-  A (sp3)

4 option- D(sp3)  

Explanation:

let Inter nuclear axis is Px

1- one s+one p orbital (s+px) = sp

as we know that total number of hybrid orbital is equal to number of orbital taking part in hybridization.

2- In h20 water o is the central atom and it has 2 bond pair and 2 lone pair and hence therefor sp3 hybridization.

3 -in nh3 ammonia n is the central atom having 3 bond pair and one lone pair and sp3 hybridized

4 -(1 s orbital + 3 p orbital px,py,pz)  sp3 hybridization
