Concept explainers
Interpretation:
The functional group in the following molecule is to be identified and each drawing has to be converted to their molecular formula.
Concept introduction:
Phenylalanine is an α-amino acid with the formula Phenylalanine is an α-amino acid with the formula C9H11NO2.
Here, the benzyl group is substituted for the methyl group of alanine, or a phenyl group in place of terminal hydrogen of alanine.
Lidocaine, also known as xylocaine and lignocaine, is a medication used to numb tissue in a specific area.
Formula: C14H22N2O
Answer to Problem 19VC
Here, Primary
Here, amide group is present as functional group in this molecule.
Explanation of Solution
From the structure of phenylalanine, it is quite evident that the terminal hydrogen of alanine is replaced by a benzyl or phenyl group.
In this way, carbon forms a covalent bond with another carbon atom or other atoms.
-NH2 group and –COOH groups are present in Phenylalanine.
-NH and C=O (Amide) groups are present as functional groups in Lidocaine.
