The condensor slopes downward so that the condensed vapour (distillate) runs out . Please note it slopes so that the liquid does NOT run back into the heated flask!
The problem with distillation is how to turn all of the hot vapour back into liquid. A simple distillation experiment using just a glass tube as a condenser, rather than a Liebig one, loses most of the steam.
The simplest method is distillation.
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
A Liebig condenser is about the most simple condenser going. It has a gas or vapor pathway that is enclosed by a jacket of through which a cooling fluid (water, maybe) is passed. The cooling fluid cools the outer surface of the vapor tube and this cooling effect reaches the inner wall of the vapor tube to cool the vapor and cause it to condense. There are a couple of nice drawings that can be viewed by using the link to our friends at Wikipedia.
Simple and steam distillation are similar in that they use boiling to separate organic components. Simple distillation boils them off at their boiling points, then condenses them. Steam distillation uses water mixed with the compounds to lower their boiling points and avoid decomposing them by heat.

The most important components of a laboratory distillation installation are: - source of heat - refrigerant (condenser) - a recipient for the liquid to be distilled - a recipient for the collected liquid after distillation - glass tubes for connections - thermometer

The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.

You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process

Yes.Because simple distillation is a separating of a mixture through heating.it is only applied to separate volatile liquid from the nonvolatile ones.The gas created by the distillation is collected through condensation to form a liquid again.Thank you '_'
