Question 10

Prefix for 10

Answer 10

Question 11

Structural formula

Answer 11

shows all hydrogens bonded to carbons; more spread out

Question 12

Condensed forumula

Answer 12

bonds written in a single line to save space

Question 13

Line formula

Answer 13

each end of the line reps a carbon and each carbon is ssumed to have the right amount of hydrogens bonded to it

Question 14

General formula for Alkanes

Answer 14

CnH2n+2

Question 15

What kind of bonds do alkanes have?

Answer 15

single

Question 16

Are alkanes saturated or unsaturated?

Answer 16

saturated

Question 17

What does it mean to be saturated?

Answer 17

each C has a max number of H’s attached; no double or triple bonds

Question 18

What kind of bond does saturated apply and do not apply to?

Answer 18

does apply to C-C, does not to C-O

Question 19

Structural Isomers

Answer 19

have the same molecular formula, but different structures and names

Question 20

General formula for Alkenes

Answer 20

CnH2n

Question 21

Are alkenes saturated or unsaturated?

Answer 21

unsaturated

Question 22

What kind of bond do alkenes have?

Answer 22

at least one double C-C bond

Question 23

What does it mean to be unsaturated?

Answer 23

there is a multiple bond and they can accept more H’s

Question 24

What should the name of an alkene end in?

Answer 24

“ene”

Question 25

General formula for alkynes

Answer 25

CnH2n-2

Question 26

Are alkynes saturated or unsaturated?

Answer 26

unsaturated

Question 27

What type of bond do alkynes have?

Answer 27

at least one triple C-C bond

Question 28

What should the name of alkynes end in?

Answer 28

"yne"

Question 29

What can be used to test for saturation in an organic compound?

Answer 29

Br2

Question 30

What color is a Br2 solution?

Answer 30

orange/reddish-brown

Question 31

What happens to bromine if added to an unsaturated solution? Why?

Answer 31

changes to colorless; dbl bond in hydrocarbon breaks and allows bromine to attach (bromine isn't Br2 anymore)

Question 32

What happens to bromine if added to a saturated solution? Why?

Answer 32

stays orange/reddish-brown; nowhere for bromine to bond

Question 33

When doing a saturation test with bromine, if a compound shows single bonds, what would the saturation be? What would happen to the color of the bromine?

Answer 33

it would be saturated and would stay orange

Question 34

When doing a saturation test with bromine, if a compound shows double/triple bonds, what would the saturation be? What would happen to the color of the bromine?

Answer 34

it would be unsaturated and would turn colorless (C-C)

Question 35

What does color change mean in terms of saturation?

Answer 35

unsaturated

Question 36

What does no color change mean in terms of saturation?

Answer 36

saturated

Question 37

General formula for cycloalkanes

Answer 37

CnH2n

Question 38

General formula for cycloalkenes

Answer 38

CnH2n-2

Question 39

Where is the double bond always located in cycloalkenes?

Answer 39

between carbon 1 and 2

Question 40

Aromatic hydrocarbons

Answer 40

contain one or more benzene rings

Question 41

Aliphatic hydrocarbons

Answer 41

(alkanes, enes, ynes, cyclic) do not contain a benzene ring

Question 42

Benzene

Answer 42

C6H6

Question 43

How to identify a benzene structure

Answer 43

has 3 alternating double bonds or has a circle in the centre of the hexane

Question 44

Phenyl vs Benzene

Answer 44

P: when benzene is as a branch B: its structure is part of the parent chain

Question 45

Alcohols

Answer 45

organic compounds with one or more hydroxyl (OH groups)

Question 46

Difference between OH- and OH

Answer 46

OH-: hydroxide, base (KOH) OH: hydroxyl, neutral (C2H5OH)
