Conditions And Reagents Flashcards
1
Q
Name the conditions to produce a diol from an alkene
A
- Oxidising Agent (KMnO4) turns purple to colourless
2
Q
Name the conditions for free radical substitution
A
UV light
3
Q
Conditions for thermal cracking
A
- Temperature = 1200K
- Pressure = 7000kPa
4
Q
Conditions for Catalytic cracking?
A
- Temperature = 720K
- Normal Pressure
- Zeolite catalyst
5
Q
Conditions for electrophilic addition to form an alkane
A
- Nickel Catalyst
6
Q
Conditions for addition reaction to form an alcohol from an alkene
A
- Steam
- acid catalyst (eg. PO4 3-)
7
Q
Conditions for diol formation
A
- Acidified potassium manganate
8
Q
Conditions for producing alcohols from halogenoalkanes
A
- aqueous potassium hydroxide (hydroxide ion acts as the nucleophilie)
9
Q
Conditions for elimination of halogenoalkanes to form alkene
A
- ethanolic potassium hydroxide (KOH) and heat
10
Q
Conditions to produce amines from halogenoalkanes
A
- alcoholic ammonia
11
Q
Conditions to produce nitriles
A
- alcoholic potassium cyanide (KCN)
(This is an example of increasing the length of the carbon chain)
12
Q
Conditions for hydration reaction (alkene -> alcohol)
A
- acid catalyst
- aqueous conditions
- temperature = 300 degrees C
13
Q
Conditions for chlorination of alcohols
A
- PCl5
- Can be used to test for alcohols as it produces steamy fumes that turn damp blue litmus paper red
14
Q
Conditions for bromination of alcohols
A
- 50% concentrated sulphuric acid
- KBr
15
Q
Conditions for iodination of alcohols
A
- Red phosphorus
- Iodine
