(a)

Interpretation Introduction

Interpretation:

Ethylpropylamine has to be classified as primary, secondary or tertiary amine.

Concept Introduction:

The structural representation of organic compound can be done in 2D and 3D.  In two-dimensional representation, there are four types of representation in which an organic compound can be drawn.  They are,

• Expanded structural formula
• Condensed structural formula
• Skeletal structural formula
• Line-angle structural formula

Structural formula which shows all the atoms in a molecule along with all the bonds that is connecting the atoms present in the molecule is known as Expanded structural formula.

Structural formula in which grouping of atoms are done and in which the central atoms along with the other atoms are connected to them are treated as group is known as Condensed structural formula.

Structural formula that shows the bonding between carbon atoms alone in the molecule ignoring the hydrogen atoms being shown explicitly is known as Skeletal structural formula.

Structural formula where a line represent carbon‑carbon bond and the carbon atom is considered to be present in each point and the end of lines is known as Line-angle structural formula.

Amine is an organic derivative.  If in ammonia one or more alkyl, cycloalkyl, or aryl groups are substituted instead of hydrogen atom then it is known as amine.  Depending on the number of substitution the amines are classified as primary, secondary or tertiary amine.  Primary amine is the one in which only one hydrogen atom in ammonia is replaced by a hydrocarbon group.  Secondary amine is the one in which only two hydrogen atoms in ammonia is replaced by a hydrocarbon group.  Tertiary amine is the one in which all three hydrogen atoms in ammonia is replaced by a hydrocarbon group.  The generalized structural formula for all the amines is,
