#1
正面 (问题)

Describe how to dustinguish between separate samples of the two stereoisomers of CH3CH2CH2CH2(OH)CN

背面 (解答)

• shine polarised light through sample • enantiomers rotate light in opposite directions

#2
正面 (问题)

Explain why a reaction produces a racemic mixture

背面 (解答)

• Planar carbonyl group • has equal chance of being attacked on either side • equal amounts of enantiomers made

#3
正面 (问题)

describe how propanone and propanal can be distinguishes using a- chemical test (3 marks) b- proton NMR spectra (2 marks)

背面 (解答)

chemical test - add feelings solution - propanal = brick red ppt - porpanone = no reaction proton NMR - propanal = 3 peaks (3 proton env) - propanone = 1 peak (1 proton env)
