Question
Chapter 14, Problem 27P
.
Interpretation Introduction
Interpretation: The chiral molecule/s needs to be identified from the three related angiotensin converting enzyme inhibitors. The number of stereoisomers possible needs to be identified for each chiral molecule. The three structures need to be compared with captopril and similarity among four drugs needs to be explained.
Concept Introduction:
A molecule is said to be chiral if it is non-superimposable with its mirror image. For example, left and right hands. These two non-superimposable mirror images of chiral molecules are known as enantiomers.

Draw structures for and name all possible stereoisomers of 2,5-dibromohex-3-ene. HINT: That means a possible total of 2³ stereoisomers, but there's also the potential for high symmetry or meso stereoisomers, which then reduces the total number of possibilities. Put boxes around pairs of enantiomers, and label meso compounds as "meso," as appropriate.arrow_forward12.

- Compound X, C,4H12Br2, is optically inactive. On treatment with strong base, X gives hydrocarbon Y, C14H10: Compound Y absorbs 2 equivalents of hydrogen when reduced over a palladium catalyst to give z (C14H14) and reacts with ozone to give one product, benzoic acid (C,Hg02).

W and X are each chiral. W reacts readily in water to form a chiral substitution product Y, CgH17OH. Reaction of a single enantiomer of W produces a single enantiomer of Y as the only substitution product. X likewise reacts readily in water though at a slower rate than W; a chiral substitution product Z, C8H₁7OH, is again formed. Unlike w, however, reaction of a single enantiomer of X produces Z that is nearly racemic. Propose structures for W and X. 0 • Do not use stereobonds in your answer.
