Concept introduction:
The functional groups are attached to carbon skeleton in any organic molecule which determines the properties of the organic molecule. Some of the functional groups are hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.
(b)
Interpretation:
The given amine needs to be labelled as 10, 20 or 30.
Concept introduction:
(c)
Interpretation:
The chiral centers of methylphenidate molecule needs to be labelled.
Concept Introduction:
The molecules with chiral center that can form superimposable mirror image and known as enantiomers. There should not be any plane of symmetry in a molecule to be chiral. A plane that bisects a molecule into two equal halves is known as a plane of symmetry. If there is a plane of symmetry in a molecule and it is identical to any of its mirror image, it is considered as achiral. The chiral center is carbon attached to 4 different groups attached to it.
(d)
Interpretation:
The 2-phenylethylamine needs to be located in methylphenidate molecule.
Concept introduction:
The functional groups are attached to carbon skeleton in any organic molecule which determines the properties of the organic molecule. The structure of 2-phenylethylamine is as follows:
(e)
Interpretation:
The structure of methylphenidatehydrochloride molecule needs to be drawn.
Concept introduction:
The functional groups are attached to carbon skeleton in any organic molecule which determines the properties of the organic molecule. Methylphenidatehydrochloride can be defined as the hydrochloride salt of methylphenidate.
