Formative A Organics Quiz

A Hydrocarbon is deemed to be saturated when...

• It has a single bond

• It has a double bond

• It is an isomer

• it has a O-H molecule

Crude oil is separated into individual hydrocarbons by

• Condensation

• Evaporation

• Fractional Distillation

• column distillation

Fossil fuels are extracted from the ground. What property allows them to be separated?

• Different melting point

• Different boiling point

• Same melting point

• Same boiling point

Moving from short chain hydrocarbons to long chain hydrocarbons, the molecules

• Have lower boiling points

• Become more volatile

• Are more gaseous

• Become more viscous

When burning short chain hydrocarbons and long chain hydrocarbons there is a difference in energy yield. Why?

• Short hydrocarbons are more volatile so they bounce around more

• Long hydrocarbons store more energy in their bonds and it is released during combustion

• Long hydrocarbons store more energy in their bonds and it is trapped during combustion

• Short hydrocarbons store more energy in their bonds and it is released during combustion

• water + carbon dioxide

• hydrogen gas

• water + soot

• Carbon monoxide + carbon + carbon dioxide + water
