Question

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

Answer 1

Answer:

1

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.
