Chapter 12, Problem 12.8E

Interpretation Introduction

(a)

Interpretation:

The structural formula for a compound with molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ that would be classified as an alkyne is to be drawn. The IUPAC name of the compound is to be stated.

Concept introduction:

The systematic naming of organic compound is given by IUPAC nomenclature. The naming of organic compound is done such that the structure of organic compound is correctly interpreted from the name.

Rules for writing IUPAC name from structural formula are:

• First identify the longest carbon chain.

• The next step is to identify the groups attached to the longest chain.

• Identify the position, location, and number of the substituents bonded to the carbon chain.

• Use prefix di, tri, tetra if same type of substituents are present.

• Name the substituents in alphabetical order.

Interpretation Introduction

(b)

Interpretation:

The structural formula for a compound with molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ that would be classified as a diene is to be drawn. The IUPAC name of the compound is to be stated.

Interpretation Introduction

(c)

Interpretation:

The structural formula for a compound with molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ that would be classified as a cyclic alkene is to be drawn. The IUPAC name of the compound is to be stated.
