IUPAC Nomenclatures

The IUPAC nomenclature of the given compound

$ \text { 6-amino-2-bromo-5-hydroxy-3-oxohexanenitrile. } $

$ \text { The correct IUPAC name of } $

$ \text { 2-ethyl-5-methylhept-1-en-6-yn-4-ol } $

IUPAC name given in option (b) is not correct. The correct IUPAC name is

The IUPAC name is

4-methyl pentoxybenzene

The correct IUPAC name is

5-amino-1-hydroxy-3-methylhex-3-en-2-one

The IUPAC name of the given compound is, 5-ethyl-9-methyldec-6-en-4-ol

The IUPAC name of the given compound is 2-ethyl-5-hydroxy-3-methyl hept-3-enal.

$ \text { The given compound is } $

Its IUPAC name is 3-ethyl-4-methylhexane.

In the given structure, numbering of functional group is done as follows:

$ \begin{aligned} & So \,\,\text {, IUPAC name will be }\\ &\begin{aligned} & \text { 6-amino-5-(2, 2-dimethylpropyl) } \\ & \text { non-4-en-3-ol. } \end{aligned} \end{aligned} $

In given structure, numbering of carbon chain is done as follows :

So, IUPAC naming will be 5-chloro-4-fluoro-4, 5-dimethylnon-7-en-3-ol.

Tertiary amines have three alkyl groups attached to - N . The parent chain is selected with the highest number of -C atoms. Other alkyl groups are treated as substituents (in this case methyl and ethyl). While naming, the suffix ' e ' of arene is replaced by 'amine' and locant N is written before each substituent name (which follows alphabetical order).

∴ The IUPAC name will be N -ethyl-N-methylbenzenamine.
