Question

Which hydrocarbon has the highest boiling point?

Answer 1

• Boiling point is the temperature at which the vapour pressure of a liquid is equal to the atmospheric pressure.
• Boiling point depends on various factors like the branching, carbon chain length, etc.
• The boiling point increases with increase in the molecular weight and number of carbons in carbon chain.
• The liquid alkane Dodecane has molecular formula ${\mathrm{CH}}_3{\left({\mathrm{CH}}_2\right)}_{10}{\mathrm{CH}}_3$ has a boiling point of around 216 degrees celsius.
