Answer 2

Heptane and sulphuric acid - effect of heating:

Explanation:

• Heptane boils at a temperature 98.38°C which is the boiling point of heptane. When it is heated , carbon-di-oxide and water vapor are released since it only involves breaking of carbon hydrogen bonds upon heating.

• Sulphuric acid boils at a much higher temperature of around 337°C . As the molecules farther apart upon heating ,then liquid sulphuric acid transforms into gaseous sulphuric acid.
• Therefore option (b) which says that heptane boils at a lower temperature than Sulphuric acid.
