Answer 1

• incomplete reaction (equilibrium)
• practical losses
• side reactions

Question 2

does silica gel act as a non polar or polar stationary phase?

Answer 2

polar

Question 3

compare rf values of larger more polar molecules with smaller less polar molecules under the same temperature and saturation

Answer 3

larger more polar molecules will have a lower rf value as they are more attracted to the stationary phase than the mobile phase
