Hydrocarbons

A hydrocarbon is
1. a suspension of carbon in water.
2. a compound made of a carbon backbone surrounded by hydrogen atoms.
3. a compound made of a hydrogen backbone surrounded with with carbon atoms.
4. an energy giving nutrient found in pasta.
Alkanes are hydrocarbons that have the general formula
1. CnHn
2. CnH2n
3. CnH(2n+1)
4. CnH(2n+2)
The first 6 alkanes are, in ascending order:
1. hexane, propane, ethane, pentane, butane, methane
2. ethane, methane, butane, propane, pentane, hexane
3. methane, ethane, propane, butane, pentane, hexane
4. pentane, hexane, butane, methane, propane, ethane.
Alkanes are held together by
1. ionic bonds
2. weak covalent bonds
3. strong covalent bonds
4. lewis diagrams
Isomers have
1. the same molecular formula, but different display formulae
2. the same molecular formula, and the same display formula
3. the different molecular formulae, but the same display formula.
4. atoms with the same number of protons, but different numbers of neutrons.
