Q. 11.61 - An Introduction to General, Organic, and Biological Chemistry

Question

Write a chemical equation for complete combustion for each of the following:

a) $2,2-$dimethylpropane

b) cyclobutane

c) $2-$hexane

Step-by-Step Solution

Answer

The chemical equations for complete combustion are:

a)${\mathrm{C}}_5{\mathrm{H}}_{12}+8{\mathrm{O}}_2⟶5{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

b)${\mathrm{C}}_4{\mathrm{H}}_8+6{\mathrm{O}}_2⟶4{\mathrm{CO}}_2+4{\mathrm{H}}_2\mathrm{O}$

c)${\mathrm{C}}_6{\mathrm{H}}_{12}+9{\mathrm{O}}_2⟶6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

Part (a) Step 1: Given information

We have to write the product after the combustion of $2,2-$dimethypropane

Part (a) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

${\mathrm{C}}_5{\mathrm{H}}_{12}+8{\mathrm{O}}_2⟶5{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

Part (b) Step 1: Given information

We have to write the product after the combustion of cyclobutane

Part (b) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

${\mathrm{C}}_4{\mathrm{H}}_8+6{\mathrm{O}}_2⟶4{\mathrm{CO}}_2+4{\mathrm{H}}_2\mathrm{O}$

Part (c) Step 1: Given information

We have to write the product after the combustion of $2-$hexane

Part (c) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

$2{\mathrm{C}}_6{\mathrm{H}}_{14}+19{\mathrm{O}}_2⟶12{\mathrm{CO}}_2+14{\mathrm{H}}_2\mathrm{O}$
