part 3 of 3
the o atom in the highlighted group.
hybridization:
molecular geometry: select

Explanation:

Step1: Determine electron - pair geometry around O

The oxygen atom in $HO - CH_2 - C\equiv CH$ has two bonding pairs (one with H and one with C) and two lone pairs. The total number of electron - pairs around the O atom is $2 + 2=4$.

Step2: Find hybridization

Based on the number of electron - pairs, the hybridization is determined by the formula: number of electron - pairs = number of hybrid orbitals. For 4 electron - pairs, the hybridization is $sp^{3}$.

Step3: Determine molecular geometry

With two bonding pairs and two lone pairs of electrons around the O atom, the molecular geometry is bent.

Answer:

Hybridization: $sp^{3}$
Molecular geometry: bent
