Passage :  

*          Three ${\text{sp}}^2$ hybrid orbitals lying in a pl$120°$ane at  angle to one another.

*          Each ${\text{sp}}^2$ hybrid orbital has  33.33% of s character and 66.66% of p character.

*          It gives trigonal shape to the molecule

Examples: ${\text{sp}}^2$ hybridization is present in $\text{BC}{l}_3,{\text{C}}_{\text{2}}{\text{H}}_4,{\text{SO}}_2,{\text{SO}}_3$, Benzene $\left({\text{C}}_{\text{6}}{\text{H}}_6\right)$, graphite,HCHO (methanol).

Q. The bond angle of ${\text{sp}}^2$ hybridization with no lone pairs is
