a. Use VSEPR to predict bond angles at the marked atom. The angle is : degrees. The expected hybridization at the marked atom is . b. Use VSEPR to predict bond angles at the marked atom. The angle is : degrees. The expected hybridization at the marked atom is .

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

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
