Answer #1

When electron domain is 2, hybridisation is sp

When electron domain is 3, hybridisation is sp2

When electron domain is 4, hybridisation is sp3

When electron domain is 5, hybridisation is sp3d

When electron domain is 6, hybridisation is sp3d2

1)

C1 forms 1 single and 1 triple bond.

So, there are 2 electron domain around C1.

This means C1 is sp hybridised

2)

C1 forms 2 single and 1 double bond.

So, there are 3 electron domain around C2.

This means C2 is sp2 hybridised

3)

O forms 2 single and has 2 lone pairs.

So, there are 4 electron domain around O.

This means O is sp3 hybridised
