Class 12th

Coca alkaloid or cocaine is obtained from Erythroxylum coca.

Functional group should get the lowest possible number.

Please find the solution below:

The boiling point of alcohol increases with increase in the number of carbon atoms. So, hexanol has maximum boiling point.

 

Complete reaction is as follows:

The given reaction is called hydroboration oxidation.

Adenine forms hydrogen bonds with thymine whereas cytosine forms hydrogen bonds with guanine.

The 'X' in reaction is 3-hydroxybutanal. It is an aldol reaction. Complete reaction is an follows:

Ethyl benzoate can be prepared by heating benzoic acid with ethyl alcohol in presence of dry HC1 or conc. The reaction is called as esterification reaction.

The carbon next to an alkene is known as allylic carbon and halogen attached to allylic carbon is known as allylic halogen.

 

Boiling points of aldehydes are higher than hydrocarbons. It is due to weak molecular association.
