Question 1

alkyene + 1 mole H =

Answer 1

Answer 2

alkane

Question 3

propene is also called..

Answer 3

propylene

Question 4

vicinal dihalide

Answer 4

when 2 halides (Br and Br) are attached to 2 carbons side by side in the products side

Question 5

solvent with bromine is (bro, clear or chill)

Answer 5

CCl4 or CH2Cl2

Question 6

it’s usually trans (bro trans)

Answer 6

bromine

Question 7

with cyclic alkenes, the reaction is usually…

Answer 7

stereospecific, or trans

Question 8

how to tell if you have a symmetrical alkene just by looking at the formula

Answer 8

CH3 - CH2 - CH = CH2. Look at the hydrogens on either side directly next to the = sign. If they are different, it’s unsymmetrical. The CH = CH2 (above) is unsymmetrical bc it’s 1 hydrogen and 2 hydrogens.

Question 9

marcovnikov’s law

Answer 9

in unsymmetrical alkene, always add the hydrogen to the carbon w/ more hydrogens, and halogens to the carbon with less hydrogens. rich get richer

Question 10

ethylene

Answer 10

H2C = CH2 - polyethylene

Question 11

propylene

Answer 11

H2C = CH - CH3 polyproplyne

Question 12

vinyl chloride

Answer 12

H2C=CH-Cl poly (vinyl chloride)

Question 13

styrene (2 stys)

Answer 13

H2C = CH (with benzene attached) polystyrene

Question 14

styrene

Answer 14

look it up

Question 15

tetraflouroethylene

Answer 15

F2C=CF2

Question 16

resonance

Answer 16

the true structure of the molecule can have double bonds in different spots, it’s 50/50. ie - benzene

phenol

Answer 17

benzene w/ OH at side chain

Question 18

toluene

Answer 18

benzene w/ CH3 at side chain

Question 19

aniline

Answer 19

benzene w/ NH2 at side chain

Question 20

naming benzene

Answer 20

1) ortho 2) meta 3) para

Question 21

ortho - O

Answer 21

side chains at 1 and 2

Question 22

meta - m-

Answer 22

side chains at 1,3

Question 23

para - p

Answer 23

side chains at 1,4

Question 24

use ortho, meta and para when..

Answer 24

there are 2 identical groups on a benzene or if there is a toulene or aniline group

Question 25

most common reaction with alkenes

Answer 25

addition

Question 26

how many H in toluene?

Answer 26

8

Question 27

how many H in toluene?

Answer 27

8

Question 28

structural isomers are constitutional isomers

Answer 28

the formula and parent are the same, but the connections are different ie. substituents are on different carbons or one has a double bond and the other doesn't, etc.

Question 29

naming benzenes (dentist first)

Answer 29

dentist first, then alphabetical 1,2; 1,3; 1;4

toulene

Answer 30

benzene w/ methyl attached

Question 31

phenol

Answer 31

easy alcohol

Question 32

aniline (Ana is nitro)

Answer 32

benzene w/ NH2 attached

Question 33

don't add a number when naming benzenes if...

Answer 33

there is only one substiuent - ie - bromobenzene

Question 34

if a benzene IS a substituent, it's called...

Answer 34

phenyl - ie 3-phenylheptane

Question 35

if benzene only has 1 branch, don't...

Answer 35

add a number

Question 36

benzene with a branch of NO2 is called...

Answer 36

nitrobenzene

Question 37

benzene as a side chain - nomenclature

Answer 37

phenyl

Question 38

if you use aniline, touleline, etc...

Answer 38

you don't need benzene at the end. These replace benzene.

Question 39

only use meta, para, or ortho IF

Answer 39

there are 2 of the same molecule branches or it's tourline, alaline, phenol

Question 40

STOP adding the number of the double bond on

Answer 40

cycloalkenes and cycloalkynes if there aren't any substituents

Question 41

also STOP adding the number to benzenes if..

Answer 41

there is only one substituent

Question 42

IF she asks on exam - when bromine is added to a cycloalkene, it's almost always cis or trans?

Answer 42

trans

Question 43

anti-addition

Answer 43

happens with cyclic alkenes - when Br (or something else is added) the product is trans, not cis

Question 44

if adding hydrohalogen using H202, go...(hydro and water are anti)

Answer 44

anti-marovnikof's rule

Question 45

if the order of the bond is different, ie 1 and 2, but everything else is the same, they are..

Answer 45

constitutional isomers

Question 46

stereoisomers have the same...
