Question

Complete and balance the given chemical reaction.
${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+{\text{O}}_2\text{(g)}\to$

• A. ${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+4{\text{O}}_2\text{(g)}\to 4{\text{CO}}_2\text{(g)}+5{\text{H}}_2\text{(g)}$
• B. ${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+{\text{O}}_2\text{(g)}\to {\text{CH}}_3{\text{CH}}_2\text{O (g)}+{\text{CH}}_3{\text{CH}}_2\text{O (g)}$
• C. $2{\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+13{\text{O}}_2\text{(g)}\to 8{\text{CO}}_2\text{(g)}+10{\text{H}}_2\text{O (l)}$
• D. $3{\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+6{\text{O}}_2\text{(g)}\to 12{\text{CH}}_3{\text{CH}}_2{\text{CH}}_2\text{O}{\text{CH}}_3\text{(g)}$

Answer 1

The correct option is C $2{\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+13{\text{O}}_2\text{(g)}\to 8{\text{CO}}_2\text{(g)}+10{\text{H}}_2\text{O (l)}$

Alkanes on heating in sufficient supply of oxygen undergoes combustion producing carbon dioxide and water.

Thus, the given reaction is an example of a combustion reaction in which butane combines with oxygen to form carbon dioxide and water.
The reaction takes place as follows:

$2{\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CH}}_3\text{(g)}+13{\text{O}}_2\text{(g)}\to 8{\text{CO}}_2\text{(g)}+10{\text{H}}_2\text{O (l)}$
