Hydrocarbons

Question 1

Covalent molecular substance

Answer 1

substance made of molecules

Question 2

Does boiling point separate atoms or molecules?

Answer 2

Molecules

Question 3

Hydrocarbons

Answer 3

compounds that contain only the elements carbon and hydrogen

Question 4

Features of hydrocarbons

Answer 4

Can contain long chains with branches; chains folded back on themselves to form rings; participate in combustion

Question 5

Alkanes

Answer 5

contains only single bonds between C atoms

Question 6

features of alkanes

Answer 6

Relatively unreactive; end in “ane”

Question 7

Acyclic alkanes

Answer 7

do not contain rings of C atoms

Question 8

Saturated hydrocarbons

Answer 8

C atoms are bonded to the max possible number of H atoms

Question 9

Condensed structural formula

Answer 9

indicate how many H atoms are bonded to each C atom

Question 10

Cycloalkane

Answer 10

has at least 1 ring of C atoms

Question 11

Degree of unsaturation

Answer 11

reduction in number of H atoms

Question 12

Alkenes

Answer 12

unsaturated hydrocarbons that contain 1 or more double bonds

Question 13

Features of alkenes

Answer 13

more reactive; “ene” in the name

Question 14

Functional group

Answer 14

an arrangement of atoms and bonds with characteristic reactivity

Question 15

Addition reaction

Answer 15

the double bond is partially broken and 2 new single bonds form

Question 16

Alkyne

Answer 16

hydrocarbon with 1 or more triple bonds

Question 17

Petroleum

Answer 17

consists primarily of naturally occurring hydrocarbons

Question 18

Fractional distillation

Answer 18

petroleum is boiled and different hydrocarbons condense to liquids at different temps

Question 19

gasoline

Answer 19

liquid mixture of linear and branched alkanes

Question 20

Catalytic cracking

Answer 20

temps and catalyst break C-C bonds and rearrange molecular strucures
