The open-chain structure of IMAGE $01$ will look like IMAGE $02$.
The open-chain structure of IMAGE $01$ will look like IMAGE $02$.
According to the structure as referring to IMAGE $02$, first of all, long chain is selected, i.e., here it is of $7$ carbon.
So, it will be named as heptane and then third and fourth carbon contains one ethyl and $2$ methyl group.
So it will be named as $3$ - Ethyl -$4, 4$-dimethylheptane.
