Question

Use the following Lewis diagram for ethyl acetate to answer the questions: H O: 12 3 Remember that geometry refers to the geometry defined by the atoms, not the electron pairs The geometry about atom C1 is The ideal value of the O-C-C angle at atom C2 is The geometry about atom Cs is degrees.

Answer 1

1)

C1 forms 3 sigma bonds and 1 pi bonds

So, C1 is sp2 hybridised since pi bond is not considered while hybridisation

the geometry is trigonal planar

Answer: trigonal planar

2)

C2 forms 4 sigma bonds

So, C2 is sp3 hybridised

the geometry is tetrahedral

so, bond angle will be 109.5 degree

Answer: 109.5 degree

3)

C3 forms 4 sigma bonds

So, C3 is sp3 hybridised

the geometry is tetrahedral

Answer: tetrahedral
