Interpretation Introduction

Interpretation:

The systematic name and given alcohol should be given and it should be classified as primary, secondary or tertiary.

Concept introduction:

IUPAC Nomenclature:

IUAC gives rules for the naming of chemical compounds. These rules are,

For saturated alcohols, longest chain with hydroxyl group is the parent chain of the compound and remaining groups and atoms are consider as substituent. In systematic name parent chain is ended with ol suffix.

In the nomenclature, Find the parent chin first then number the carbon atoms in the parent chain by giving lowest number to the hydroxyl substituted carbon followed by designate the other substituent in its position in parent chain.

If more than one same substituent or hydroxyl groups were occurs, add a prefix (di-, tri-, tetra-, ect..) in front of parent chain name.

Finally the systematic name was written as, the substituent position number with prefix (di-, tri-, tetra-, ect..) of number of substituents followed by name of the substituent then write the parent chain name (which contains large number of carbon atoms in the chain).

Alcohols:

In organic chemistry alcohols are types of compounds, which are having one or more than one hydroxyl group connected with a Carbon atom in a molecule.

In primary alcohols, hydroxyl group is connected with carbon, which is connected with all hydrogen or connected with single carbon substituent.

In secondary alcohols, the hydroxyl group is connected with carbon, which is connected two alkyl or aryl substituents.

In tertiary alcohols, the hydroxyl group is connected with carbon, which is connected two alkyl or aryl substituents.
