In fractional distillation how are substances separated in this particular instance Isopropanol(ethanol) and water to separate both substances and collect them as pure substances separated

A water and ethanol mixture is heated in a flask using an electric heater. Vapour forms in the air above the mixture in the flask.
The boiling point of ethanol is 78°C. Ethanol vapour passes into the condenser, where it is cooled and condensed. Liquid ethanol drips into a beaker.
When most of the ethanol has left, water vapour at 100°C passes into the condenser, where it is cooled and condensed. Liquid water now drips into the beaker.

Fractional would involve boiling everything then having a fractionating tower inside which be different temperatures allowing different fractions (gases that condense at certain temperatures) to condense. Think crude oil - a very complex mixture.
Simple distillation (as hexadentate) described will do nicely.

You wouldn't use fractional distillation, just the normal one would do.

yes but the question i am answering is asking how it would be separated using fractional distillation

Research frac. dist. of crude oil for more detail.
