Reactions!!!! Flashcards
1
Q
Alkane -> Molohaloalkane
A
free radical substitution
- UV light
- X2
2
Q
Alkene -> Molohaloalkane
A
Electrophilic addition
- HX (delta +/-)
- RTP
- two possible products
- heterolytic fission breaks H-X bond
3
Q
Alcohol -> Molohaloalkane
A
NaX and H2SO4 form HX in situ
- heat under reflux
alcohol + HX -> haloalkane + H2O
4
Q
Molohaloalkane -> Alcohol
A
Nucleophilic substitution - heat under reflux - NaOH (provides OH nucleophile) - C-X bond breaks by heterolytic fission haloalkane + OH- -> alcohol + X-
rate of hydrolysis can be measured
5
Q
Alcohol -> Alkene
A
- heat under reflux
- conc acid catalyst (H2SO4/H3PO4)
removal of water
6
Q
Alkene -> Alcohol
A
Electrophilic addition
- H2O (g)
- H3PO4 catalyst
two possible productsq
7
Q
Alkene -> Alkane
A
Electrophilic addition hydrogenation - H2 - Ni catalyst - high temp
8
Q
Alkene -> Dihaloalkane
A
Electrophilic addition halogenation - X2 - RTP - used as a test for C=C bonds w/ bromine water
9
Q
Alkene -> Addition polymer
A
addition polymerisation
- high temp & pressure (polyethene) or catalyst
10
Q
Primary Alcohol -> Aldehyde
A
- acidified potassium dichromate [O]
- distill
11
Q
Primary Alcohol -> Carboxylic Acid
A
- acificied potassium dichromate in excess 2[O]
12
Q
Secondary Alcohol -> Ketone
A
acificied potassium dichromate
13
Q
Alcohol -> Ester
A
- heat under reflux
- conc H2SO4
- CH3COOH
