Concept explainers
Assign priorities to the groups in each set.
- (a) —H —CH3 —OH —CH2OH
- (b) —CH2CH=CH2 —CH=CH2 —CH3 —CH2COOH
- (c) —CH3 —H —COO–—NH3+
- (d) —CH3 —CH2SH —NH3+ —CHO
(a)
Interpretation:
Priorities to the given groups has to be assigned.
Concept Introduction:
Priority rules:
- Priorities based on atomic number
- When priority cannot be assigned on the basis of the atoms bonded directly to the chiral center
- Atoms participating in a double or triple bond are considered to be bonded to an equivalent number of phantom atoms.
For example,
- Priority assignment is made at the first point of difference between groups (should not be based on the larger group).
Explanation of Solution
Given groups,
Assign priorities to the given groups based on the priority rules,
(b)

The reaction is stereospecific—that is, the stereoisomers obtained as products depend on the stereoisomer used as a reactant. Recall that because 2-acetoxycyclohexyl tosylate has two asymmetric centers, it has four stereoisomers—two are cis and two are trans. Explain the following observations:a. Both cis reactants form an optically active trans product, but each cis reactant forms a different trans product.b. Both trans reactants form the same racemic mixture.c. A trans reactant is more reactive than a cis reactant.arrow_forward2-Acetoxycyclohexyl tosylate reacts with acetate ion to form 1,2-cyclohexanediol diacetate.
