Chapter 22 - Hydrocarbon Compounds Flashcards
What does a hydrocarbon contain? What are the two simplest hydrocarbons?
It contains only carbon and hydrogen. Methane and ethane.
What are the simplest organic compounds?
Hydrocarbons.
Why do carbon atoms form 4 covalent bonds?
Because carbon has 4 valence electrons.
Explain the general rule, “like dissolves like.”
2 non polar compounds will form a solution, as will 2 polar compounds. However, a polar compound and a non polar compound will not form a solution. Ex: oil is a mixture of hydrocarbons, so oil and water do not mix.
What’s an alkane?
A hydrocarbon in which there are only single covalent bonds.
What’s an alkene?
It’s a hydrocarbon that contains one or more C—C double covalent bonds.
Describe the bonding between atoms in an alkene.
At least one C—C double bond is present in an alkene. Other bonds may be single C—C bonds or C—H bonds.
What’s an alkyne?
A hydrocarbon than contains one or more C—C triple covalent bonds.
What types of bonds are present in an alkyne?
At least 1 C—C triple bond is present. Other bonds may be single or double C—C and C—H bonds.
What are the kind of attractions between alkanes, alkenes, and alkynes?
Weak Van der Waals forces.
Define isomers.
Compounds that have the same molecular formula but different molecular structures. (Other properties differ too)
