Question

Which functional group is not present in this molecule?

a. Carboxyl

b. Sulfhydryl

c. Hydroxyl

d. Amino

Answer “Which functional group is not present in this molecule?”.

Organic Chemistry:

Organic chemistry is an additional branch of chemistry that includes inorganic and physical. It deals with compounds where carbon atoms are held together through covalent bonds. With side chains of inorganic or carbon-based groups, long chains of carbon atoms can be made. Functional groups are key to the chemistry of organic molecules.

Carboxyl group

A carboxyl functional group (-COOH) is one where a carbon is bound with an hydroxyl (OH) group, and also connected to another oxygen atom with a double-bond. Many biological molecules such as proteins rely on carboxyl groups. Amino acids are the building blocks of proteins. They contain both an amine and a carboxyl groups. This functional group allows amino acid to be linked together in long strands, which make proteins.

Sulfhydryl group

The Sulfhydryl family refers to organic compounds that have an R group that is bonded to both a sulphur and hydrogen atom. Sulfhydryl compounds are moderately polar and have low boiling points. Vitamin B-1 and the amino acid cysteine are two examples of the Sulfhydryl groups.

Amino Acids

Amino acids are the monomer units that comprise proteins and small peptides. There are 20 essential amino acids, which can be grouped according to their chemical properties.

Hydroxyl group

A hydroxyl functional group (-OH)  is one that has both an oxygen and hydrogen atom at the hydrocarbon chains. It can also be called an alcohol group.

Answer

A amino functional groups is R –

A hydroxyl functional group is R – OH

A sulfhydryl functional group is R – SH

A carboxyl functional group is R – COOH

Then, in the picture we have 3 functional group are amino functional group, hydroxyl functional group, carboxyl functional group and we don’t have sulfhydryl functional group

=> The last result is b. sulfhydryl functional group.
