Chapter 11, Problem 11.44P

Interpretation Introduction

Interpretation:

The general relation between the density of alkanes and density of water should be explained.

Concept Introduction:

Alkane is a long chain of carbon linked with only single bond between each carbon. Formula of alkane is C_n H_{2n +2} where, n is number of carbon atom. Alkane produces or liberates energy on combustion along with the formation of carbon dioxide and water.

Straight chain has large surface area which increases the possibility of area of contact with other chain and result in sideways overlapping which results in higher vander waal forces between them and thus condenses the structure.
