While separating a mixture of ortho- and para-nitrophenols steam distillation, name the isomer which will be steam volatile. Give reason.

Text Solution

AI Generated Solution

To solve the question regarding the steam volatility of ortho- and para-nitrophenols, we need to analyze the molecular structures and the types of hydrogen bonding present in each isomer. ### Step-by-Step Solution: 1. **Identify the Structures of the Isomers**: - Ortho-nitrophenol (o-nitrophenol) has the nitro group (-NO2) and hydroxyl group (-OH) on adjacent carbon atoms of the benzene ring. - Para-nitrophenol (p-nitrophenol) has the nitro group and hydroxyl group on opposite sides of the benzene ring. ...

    Amit was asked by his teacher to separate a liquid mixture of acetone and ethyl alcohol. He set up a distillation apparatus and tried to distil the mixture. To his surprise, both the liquids got distilled. Teacher told Amit to repeat the experiment by using a fractionating column in the distillation flask. Amit followed the advice of the teacher and was able to separate the two liquids. (i) Why was Amit not successful in separating the liquid mixture earlier ? (ii) Why did teacher ask him to use the fractionating column ? (iii) Which liquid was distilled first ? (iv) As a student of chemistry, what value based information you have gathered ?
