Interpretation Introduction

Interpretation:

The functional groups present in propranolol have to be identified. The structures of propranolol and epinephrine have to be compared and similarities and differences between them has to be identified.

Concept Introduction:

Functional group: They are certain substitutes in the organic molecules which are determine the characteristic reactions taking place in it.

Amide: One $-N{H}_2$, $-NHR\text{'}$ or $-NR{\text{'}}_2$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCONR{\text{'}}_2$.

Alcohol: It is an organic compound where it contains at least one $-OH$ group. It is represented as $ROH$.

Ether: Ether is a group of organic compound where two aryl or alkyl groups are connected by an oxygen atom. It is represented as $ROR\text{'}$.

Amines are the derivatives of ammonia $\left(N{H}_3\right)$ with one or more of the hydrogens replaced with a substituent such as an alkyl group.

Depending on the number of carbon side chain of the nitrogen, different types of amines can form.

Aromatic Compounds: Compounds that are planar, conjucate, cyclic and having $\left(4n+2\right)\pi$ electrons are known as aromatic compounds.
