Question

a hybrid orbital set is shown below. how many unhybridized p - orbitals does it have?

Explanation:

Step1: Determine the hybridization type

The hybrid orbital set has 2 hybrid orbitals. According to the hybridization rule, the formula for the number of hybrid orbitals is \(n\). If \(n = 2\), the hybridization is \(sp\) hybridization.

Step2: Calculate the number of unhybridized \(p\) - orbitals

The total number of \(p\) - orbitals in a valence shell is 3 (\(p_x\), \(p_y\), \(p_z\)). For \(sp\) hybridization, 1 \(s\) orbital and 1 \(p\) orbital are hybridized. So the number of unhybridized \(p\) - orbitals is \(3 - 1=2\).

Answer:
