Question

5. According to Crams rule a-Phenylpropionaldehyde reacts with methylmagnesium bromide to
form
a. erythro 3-phenyl-butanol-2-ol
b. threo 3-phenyl-butanol-2-ol
c. both threo and erythro 3-phenyl-butanol-2-ol with predominance of erythro isomer
d. both threo and erythro 3-phenyl-butanol-2-ol with predominance of threo isomer​

Answer 1

Explanation:

Given a combination of atoms expressed only by a molecular formula, many quite different molecular structures that differ from each other in the nature or sequence of bonding of the atoms in space are possible. Each individual molecular assembly is called an isomer, and the constitution of a compound is a particular combination of bonds and sequences of atoms of given molecular formula. For example, propanal, acetone, cyclopropanol, and 2-methyloxirane each correspond to the molecular formula C3H6O, but differ in constitution.
