Dimethyl ether and ethanol are structural isomers of C2H6O. Which one will have a higher boiling point? Explain why and do the same for their melting points.
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, howeve
