What two methods could be used to purify the dimethyl fumarate?
Based on the 12 Principles of Green Chemistry posted in the
Green Chemistry Module, list 3 principles that are used in this
experiment. The experiment: Isomers and Isomerization
B: Isomerization of Dimethyl Maleate
Homework Answers
ANS:- purification of Dimethyl fumrate
1. it can be washed with ethanol ,ethanol dissolve all its impurities and purified product will filter out..
method :-
- take 100 gm Dimethyl Fumrate in 500 ml beaker .
- add 200 ml ethanol and stirrer with glass rod
- and filter
- add 200 ml ethanol more in filtered dimethyle fumrate
- stirrer,filter and evaporate methanol to dry.
- pure product collect.
2.it can be purified by flash chromatography.
method:-
- mobile phase - methanol water ratio 70 : 30

Two light sources are used in a photoelectric experiment to determine the work function for a particular metal surface. When green light from a mercury lamp (A 546.1 nm) is used, a stopping potential of 0.802 V reduces the photocurrent to zero. (a) Based on this measurement, what is the work function for this metal? eV (b) What stopping potential would be observed when using light from a red lamp (A 686.0 nm)? V
