1.2 Alkenes and Alkynes

Question 1

Unsaturated Carbon

Answer 1

An organic compound, consisting of Carbon and hydrogen, with one or more double or triple bonds joining pairs of carbon atoms within the molecules

Question 2

Alkene

Answer 2

A hydrocarbon that contains at least one carbon-carbon double bond

Question 3

Alkyne

Answer 3

A hydrocarbon that contains at least one carbon-carbon triple bond

Question 4

Aliphatic hydrocarbon

Answer 4

A compound that has a structure based on straight or branched chains or rings of carbon atoms

Question 5

Stereoisomers

Answer 5

Molecules that have the same chemical formula and structural backbone, but with a different arrangement of atoms in space

Question 6

Cis isomer

Answer 6

A stereoisomer in which the groups of interest are located on the same side of a double bond

Question 6

Trans isomer

Answer 6

A stereoisomer in which the groups of interest are located on opposite sides of a double bond

Question 7

Addition rxn

Answer 7

A rxn in which the atoms from one molecules are added to another molecule to form a single molecule

Question 7

Functional group

Answer 7

A group of atoms within a molecule that determines the molecule’s properties

Question 8

Markonikov’s rule

Answer 8

The rule for predicting the products of addition rxns: when a hydrogen halide or water is added to an alkene, the hydrogen atom generally bonds to the carbon atom within the double bond that already has more hydrogen atoms bonded to it

Question 9

4 Addition rxns

Answer 9

Hydrogenation, halogenation, hydrohalogentation, and hydration
