Question

How many of the following molecules contain at least one atom in sp hybridization
HC = C = CH, CH3-C = CH, CH2 = C = 0, CO2, SO2​

Answer 1

Answer:

In ground state, boron has 2 electrons in s orbital and 1 electron in p orbital, in excited state one electron jump from s to p orbital and thus we get 3 atomic orbitals for bonding which have unpaired electrons.

1 s and 2 p,

Thus, BF

3

forms three sp

2

hybridized orbitals.
