Question

The list below includes some of the properties of butane, a common fuel. Identify the chemical properties in the list. Check all of the boxes that apply.denser than water
burns readily in air

boiling point of –1.1°C

odorless

does not react with water

Answer 1

the answer is just 2 and 5

Answer 2

Explanation:

Butane is a four member carbon chain.

The properties of butane are as follows.

• Butane is less denser than water.
• In the presence of air, it readily burns to form water vapour and carbon dioxide. The reaction is as follows.

           $2C_{4}H_{10} + 13O_{2}(g) \rightarrow 8CO_{2}(g) + 10H_{2}O(aq)$

• It has a boiling point of $-11.7^0C$.
• Butane has faint petroleum like odor.
• Butane does not react with water.

Butane has weak dispersion force and water has strong hydrogen bonding.  The weak dispersion force is unable to break the hydrogen bonding hence, butane does not dissolve in water.

Thus, we can conclude that the chemical properties butane burns readily in air and does not react with water are true out of the given list of options.
