Question

Problem Set 9 me: CH3 CH3:O: H3C CH3 b | CH3 1) Retinal (structu re above) in conjunction with rhodopsin is important for the

using the above structure and looking at the methyl group (-CH3) in box a, please answer the following questions:

a) how many electron domains surround the carbon of the methyl group in box a

b) based on the number of electron domains, what is the geometry of that carbon?

c) based on the geometry, what is the hybridization of carbon?

d) given the geometry and hybridization, what are the bond angles around that carbon?

Answer 1

Number of bonded atoms +Number of lone pairs The electron domains on the atom a) Number of electron domains = 4 b) Geometry of the carbon atom tetrahedral c) Hybridization= sp3 d) Bond angle 109.50
