Chapter 7.4, Problem 9P

Interpretation Introduction

Interpretation:

The smallest alkane, smallest terminal alkene and smallest terminal alkyne which are liquids at room temperature should be identified from the given table.

Concept Introduction:

Physical properties of hydrocarbons:

• The compounds with high molecular weight have high boiling point.
• Insoluble in water, but in polar solvent it is stable.
• Density of hydrocarbons are less than of water.

Polarity is an important factor in comparing the boiling points of two compounds.  The more dipole moment, more will be the boiling point.
