The molecular formula for the given alkane is to be given and it is to be represented by a condensed formula. Concept Introduction: Alkanes are the simplest hydrocarbons having single bonds. In alkanes, each carbon atom has four single bonds. In bond line formulas, labels for individual carbon atoms are omitted, and hydrogen atoms attached to carbon atoms are shown only when necessary. A molecular formula is determined from a bond line formula by counting the number of carbon atoms in it. The general molecular formula for alkanes is C n H 2n+2 . Applying this formula, the number of hydrogen atoms for the given bond line formula is calculated. In a condensed formula, the bonds between atoms are omitted. Two methyl groups at either end are written. The total number of methylene carbon atoms between the two terminal methyl groups is written as a subscript in the parentheses.

Interpretation Introduction

Interpretation:

The molecular formula for the given alkane is to be given and it is to be represented by a condensed formula.

Concept Introduction:

Alkanes are the simplest hydrocarbons having single bonds. In alkanes, each carbon atom has four single bonds.

In bond line formulas, labels for individual carbon atoms are omitted, and hydrogen atoms attached to carbon atoms are shown only when necessary.

A molecular formula is determined from a bond line formula by counting the number of carbon atoms in it. The general molecular formula for alkanes is CnH2n+2. Applying this formula, the number of hydrogen atoms for the given bond line formula is calculated.

In a condensed formula, the bonds between atoms are omitted. Two methyl groups at either end are written. The total number of methylene carbon atoms between the two terminal methyl groups is written as a subscript in the parentheses.
