1. Which elements are found in all hydrocarbon compounds?
1) Carbon and nitrogen 3) Hydrogen and nitrogen
2) Carbon and hydrogen
4) Hydrogen and oxygen
2. A carbon atom in a hydrocarbon molecule can form
1) Single bond, only 3) Triple bonds, only
2) Double bonds, only 4) Either single, double, or triple bond

1) A periodic series 3) An Actinide series
2) A homologous series 4) A lanthanide series
4. Which list of compounds contains only hydrocarbon?
1) Alkanes, alcohols, aldehydes 3) Alkanes, alkenes, and halides
2) Alkanes, alkenes, and alkynes 4) Alkynes, amines, and alcohols
5. In a given homologous series of hydrocarbons, the boiling point generally increases as the size of the
molecules increases. The best explanation for this statement is that in larger organic molecules
1) The number of covalent bonds per molecule is greater
2) The molecules are more symmetrical
3) There more hydrogen bonding possible
4) There are greater intermolecular forces
3. Saturated hydrocarbons: Recalling concept facts and definitions
1. In saturated hydrocarbons, carbon atoms are bonded to each other by
1) Single covalent bonds 3) Triple covalent bonds
2) Double covalent bonds 4) Coordinate covalent bonds
2. The total number of electrons shared between two adjacent carbon atoms in a saturated
hydrocarbon is
1) 1 3) 3
2) 2 4) 4
3. The number of pair of electrons needed to form a single covalent bond between two adjacent
carbon atoms in a saturated hydrocarbon is 3) 3
1) 1
2) 2 4) 4
4. Which series of hydrocarbon contains saturated molecules?
1) Alkyne series
3) Alkane series
2) Alkene series 4) Alkyl series
5. Which general formula is possible for all saturated hydrocarbon molecules?
3) CnH2n-2
1) CnH2n
2) CnH2n+2 4) CnH2n+6
