Question 1

vacuum distillation

Answer 1

ideal for boiling points for 150 degrees celsius bc it lowers air pressure which in turn lowers boiling point

Question 2

boiling chips

Answer 2

prevent superheating by providing nucleation sites for bubbles to form

Question 3

simple distillation

Answer 3

boiling points under 150 and atleast 25 degrees celsius apart

Question 4

effects of branching on boiling point

Answer 4

branching decreases surface area which decreases boiling point

Question 5

enamine vs imine formation

Answer 5

enamine: secondary amine + aldehyde or ketone under acidic conditions

imine: primary amine + aldehyde or ketone under acidic conditions
