Question

Give the IUPAC name of the following alcohols. Classify as primary or secondary or tertiary alcohol.

Answer 1

Hint: In organic chemistry, the naming of the compounds is done according to the standards that are laid by the IUPAC which is the acronym for the International Union of Pure and Applied Chemistry. By naming the compound, its structure also can be deducted.

Complete step by step answer:
The IUPAC has led to certain rules for the naming of the organic compounds which describe the structure of the compound. The naming according to the standards of the IUPAC is the standard manner of naming a compound but the trivial or the common names are usually preferred as they are much shorter and easy to remember.
The IUPAC name of the compounds has certain rules which include the naming of the functional group at the last and the substituent groups at the start with the position at which they are attached. All this is provided to get the structure of the compound.

The IUPAC name of the given compound is 1-phenyl but-3-en-2-ol. Since the alcohol group is attached to the secondary carbon so the compound is a secondary alcohol.

Note: Carbon is a tetravalent atom which means it has four valence electrons and thus can form four covalent bonds with atoms.
Based on this property the carbon atom can be categorized as primary, secondary, or tertiary
The carbon which is attached to only one other carbon atom is called primary carbon, the carbon atom with the attachment of two other carbon atoms is secondary carbon whereas the carbon atom with the attachment of three carbon atoms is termed as a tertiary carbon atom.
