Question

write IUPAC name of the following structure

Answer 1

3,4-diethylhexane

IUPAC name of the given structure

Answer 2

Answer:

3-Ethyl 4,4 Dimethyl Heptane

Explanation:

Reason:

• The longest main chain is 7 carbons long. Word Root will be 'Hept-'

• There is an ethyl group on 3rd carbon. So Primary prefix is '3-Ethyl'

• There are 2 methyl groups on 4th carbon. So Primary suffix is '4,4-Dimethyl'

• There is no double/triple bond so primary suffix is '-ane'.

NOTE

( Secondary Prefix + Primary Prefix + Word Root + 1° suffix + 2° suffix)

( Substituents  + Cyclo/bicyclo + Carbon atom number + saturation(double triple bond)    + Functional group )
