Concept explainers
(a)
Interpretation:
All the carbon stereoisomers in a cholesterol molecule needs to be identified.
Concept Introduction:
A stereocenter is a carbon atom that is bonded to four different groups. It is also called a chiral carbon atom.
(b)
Interpretation:
The number of possible stereoisomers should be determined.
Concept Introduction:
A stereocenter is a carbon atom that is bonded to four different groups. It is also called a chiral carbon atom. If there are n stereocenters in a compound the number of stereoisomers can be calculated using the formula: 2n.
(c)
Interpretation:
The number of the stereoisomers of cholesterol present in the nature should be determined.
Concept Introduction:
A stereocenter is a carbon atom that is bonded to four different groups. It is also called a chiral carbon atom. If there are n stereocenters in a compound the number of stereoisomers can be calculated using the formula: 2n.
