Question

The molecule shown below has bow many chiral carbons? a. One b. Two c. Three d. Four The following pair of compounds are related as: a. Identical b. Enantiomers c. Diastereomers d. Constitutional isomers When acetamide undergoes alkaline hydrolysis (NaOH), what products are formed? a. Sodium acetate and ammonia b. Nitrogen, carbon dioxide, and sodium hydroxide c. Ammonia and sodium carbonate d. None of the above The structure of epinephrine is shown below. Is this a primary, secondary, tertiary, or quaternary amine? a. Primary b. Secondary c. Tertiary d. Quaternary

Explanation / Answer

First, define/identify the CHIRAL center, recal that the chiral center must be bonded to 4 different types of "branches" that is, they should NOT repeat each other, such as CH3, CH3.. It should have all 4 substituents completely different.

then, from the previous example:

the 6ringed carbon has 1 chiral carbon

the carbon bonded to Cl/CH3/H and rest of molcuel is also chiral

so n = 2 chiral centers

Q2.

these are mirror images

therefore enantiomers
