General And Organic Chemistry - Lecture 10 - Alkanes And Cycloalkanes

1. What is a hydrocarbon?

A compund composed of only carbon and hydrogen.

A compound composed of oxygen and hydrogen.

A compound composed of nitrogen and hydrogen.

A compound composed of carbon, hydrogen, and oxygen.

A hydrocarbon is specifically a compound that only contains carbon and hydrogen atoms.

Explanation

A hydrocarbon is specifically a compound that only contains carbon and hydrogen atoms.

2. What are the 4 different types of hydrocarbons?

Alkanes (Chapter 11) - Only carbon-carbon single bonds
Alkenes (Chapter 12) - One or more carbon-carbon double bond
Alkynes (Chapter 12) - one or more carbon-carbon triple bond
Arenes (Chapter 13) - One or more benzene-like rings

Isotopes

Isomers

Polymers

The correct answer lists the four different types of hydrocarbons as alkanes, alkenes, alkynes, and arenes, each with distinct structural characteristics.

3. What is an alkane?

Hydrocarbons containing only carbon-carbon single bones.

Hydrocarbons containing carbon-carbon triple bonds.

Hydrocarbons containing carbon-nitrogen bonds.

Hydrocarbons containing carbon-carbon double bonds.

Alkanes are saturated hydrocarbons, meaning they contain only carbon-carbon single bonds. This distinguishes them from alkenes, which contain at least one carbon-carbon double bond, and alkynes, which contain at least one carbon-carbon triple bond. Alkanes do not contain any carbon-nitrogen bonds.

4. What is a line-angle formula?

Line-angle formulas are used for representing non-carbon atoms only.

A line-angle formula only shows hydrogen atoms.

A vertex in line-angle formulas does not represent a carbon atom.

A line represents a carbon-carbon bond and a vertex and a line terminus represent a carbon atom.
Hydrogen atoms are not shown in line-angle formulas.

A line-angle formula is a way of representing organic molecules where lines represent carbon-carbon bonds and vertices/line termini represent carbon atoms, with the convention of not showing hydrogen atoms.

5. What are the names of the first 10 alkanes?

Methene, Ethan, Propanol, Butylene, Pentene, Hexanol, Heptene, Octene, Nonanol, Decene

Alkanes are a type of hydrocarbon compound with single bonds between carbon atoms. Each alkane has a specific number of carbon atoms, with the first 10 starting from methane, which has one carbon atom, and increasing by one carbon atom for each subsequent alkane.
