One of the factors that affect the boiling point of compounds is molecular weight – higher molecular weight means higher boiling point due to increasing intramolecular forces of attraction. Which will be isolated first if a mixture of the following will be separated by distillation? O a. Diethyl ether (C4H100) O b. Dipropyl ether (C6H140) Oc. Butyl propyl ether (C7H160) O d. Ethyl propyl ether (C5H120)

Question
Hi! I really need help on these three questions about simple distillation. I have no questions left so i really hope that you'd answer all these three. Thank u!
Transcribed Image Text:One of the factors that affect the boiling point of compounds is molecular weight – higher molecular weight
means higher boiling point due to increasing intramolecular forces of attraction. Which will be isolated first if a
mixture of the following will be separated by distillation?
O a. Diethyl ether (C4H100)
O b. Dipropyl ether (C6H140)
O c. Butyl propyl ether (C7H160)
O d. Ethyl propyl ether (C5H120)
If the first 1 mL distillate is not removed, there will be a/an
in the purity and
in the per cent
yield.
O a. Decrease; decrease
O b. Decrease; increase
O c. No effect; increase
O d. Decrease; no effect
Which of the following is FALSE regarding a distillation set-up?
Select one:
O a. Boiling chips are placed in the distilling flask.
O b. The water around the condenser is kept cool to increase recovery.
O c. The first twenty drops of the distillate are discarded.
O d. The water outlet is located closer to the receiving flask.
