Question

The IUPAC Name of ${\left({\mathrm{CH}}_3\right)}_3{\mathrm{CCH}}_2\mathrm{CH}\left(\mathrm{Br}\right){\mathrm{C}}_6{\mathrm{H}}_5$ Is

Answer 1

International Union of Pure and Applied Chemistry (IUPAC) nomenclature :

• The International Union of Pure and Applied Chemistry (IUPAC) nomenclature of organic chemistry is a system for naming organic chemical compounds in chemical nomenclature.
• It is compiled in the Nomenclature of Organic Chemistry.

Naming of ${\left({\mathrm{CH}}_3\right)}_3{\mathrm{CCH}}_2\mathrm{CH}\left(\mathrm{Br}\right){\mathrm{C}}_6{\mathrm{H}}_5$:

• Since there are 4 carbons in the carbon chain so the compound will have the root word “but”.
• since there is one bromine atom attached to the first carbon atom, so prefix $1-$ Bromo will be used
• Since there are two methyl groups present on the third carbon of the carbon chain, so prefix $3,3-$ dimethyl will be used.
• Since the phenyl group is attached to the first carbon atom $1-$phenyl prefix is used.
• Now, we will arrange these all subgroups according to their alphabetic order

So the IUPAC name of ${\left({\mathrm{CH}}_3\right)}_3{\mathrm{CCH}}_2\mathrm{CH}\left(\mathrm{Br}\right){\mathrm{C}}_6{\mathrm{H}}_5$ is 1-Bromo-3,3-dimethyl-1-phenylbutane.
