Organic Synthesis Flashcards
1
Q
What is the colour change for alcohol after reacting K2Cr2O7
A
Orange to green
2
Q
How to test for carboxylic acid
A
Na2Co3 and positive result is cloudy limewater
3
Q
How to test for phenol
A
NaOH then Na2CO3 and positive results indicates colourless solution with NaOH with lack of effervescence with Na2CO3
4
Q
What occurs when you do chromotography with a polar solvent
A
A.A travels further up the plane as A.A is more soluble
5
Q
How can chromotgram be used to identify A.A
A
Calculate rF Val. and compare to known val.
6
Q
How does gas chromotography seperate contents in a mixture
A
Relative solubility in stationary phase
7
Q
What is isoelectric phase
A
pH at which A.A has no overall charge ( AT low pH - NH3+ / AT high pH - COO-)
