Question

As the number of carbons in the hydrocarbon increases, the boiling point

increases or decreases

Answer 1

Increases

Step-by-step explanation:

As the number of carbons in the hydrocarbon increases, the boiling point of increases and volatility reduces.

The increasing number of carbon atoms increases the molecular mass and this will eventually lead to a higher boiling point.

• With increasing chain length, hydrocarbons tends towards liquid and solid phases.
• This increase leads to a greater intermolecular interaction in the compound.
• Intermolecular forces determines the boiling point of hydrocarbons.
• This is why gasoline is easily combusted compared to lubricant oil.
