PURIFICATION AND CHARACTERISATION OF ORGANIC COMP Quiz

• It decomposes
• It moves into the solvent where it is more soluble
• It evaporates
• It solidifies

• It increases the pressure
• It lowers the boiling point of the compound
• It adds color
• It neutralizes acids

• Solid adsorbent
• Gas like nitrogen
• Solvent or mixture of solvents
• Electric current

• They prevent resonance
• They increase molecular mass only
• They can participate in electron delocalization if adjacent to a π-system
• They are always non-reactive

• To reduce cost
• To add color
• To safely achieve and maintain temperatures above the boiling point of the test compound
• To make the liquid boil faster
