To draw the skeleton diagram for 3-ethyl-3,4-dimethylhexane, we need to determine the arrangement of carbon atoms and their connections. Let's break down the name and analyze the structure step by step:
Hexane: Hexane is a hydrocarbon with six carbon atoms in a straight chain. The skeletal structure of hexane looks like this:
H H H H H H | | | | | | H-C-C-C-C-C-C-H | | | | | | H H H H H H
Dimethylhexane: "Dimethyl" indicates that two methyl (-CH3) groups are attached to the hexane chain. We can add them to carbon atoms at positions 3 and 4:
H H H H H H | | | | | | H-C-C-C-C-C-C-H | | | | | H H H H H | CH3
3-ethyl-3,4-dimethylhexane: "3-ethyl" means there is an ethyl (-CH2CH3) group attached to carbon atom 3. Let's add it to the structure:
H H H H H H | | | | | | H-C-C-C-C-C-C-H | | | | | H H H H H |
CH3 | CH2CH3
Combining all the substitutions, the skeletal structure of 3-ethyl-3,4-dimethylhexane looks like this:
