Answer: Hello your question is incomplete attached below is the complete question with the missing diagrams
a) The angle = 120°
hybridization = sp2
b) The angle = 120°
hybridization = sp2
Step-by-step explanation:
a) using VSPER to predict bond angles
Given that there is the presence of 1 double bond to C and 2 single bonds one to C and one to H around the marked atom which equals 3 sets of electrons surrounding the central atom.
hence according to VSPER theory the angle = 120° while the Hybridization = sp2
b) Using VSPER to predict bond angles at marked atom
Given that there is There is 1 double bond to C and 2 single bonds to the different C atoms respectively around the marked atom, which makes 3 sets of electorns surrounding the central atom
hence according to VSPER theory the angle = 120° while the Hybridization = sp2
