Question

How many unhybridized p atomic orbitals are present when a central atom exhibits trigonal planar geometry?

Answer 1

1

Step-by-step explanation:

Trigonal planar geometry is shown by the compounds where hybridization of central atom is
`sp^2`.

In
`sp^2` hybridization, three hybrid orbitals are equally spaced at an angle of 120°.

Some of the compounds having
`sp^2` hybridization are
`CO_3^(2-)`,
`SO_3`, etc

In
`sp^2` hybridizationm, one s-orbital and 2 p-orbitals are involved.

Total no. of orbitals present in p-subshell is 3.

As 2 is involved in
`sp^2` hybridization, therefore no. of unhybridized orbital in
`sp^2` hybridization is 1.
