Answer : The name of the given hydrocarbon is, 3,3-dimethylhexane
Explanation :
The basic rules for naming of organic compounds are :
- First select the longest possible carbon chain.
- The longest possible carbon chain should include the carbons of double or triple bonds.
- The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne and carboxylic acid by adding the suffix -oic acid.
- The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.
- The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.
- If two or more similar alkyl groups are present in a compound, the words di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.
From the given structure we conclude that, the longest carbon contains 4 carbons and two methyl group are present at 3rd position.
So, the name of the given hydrocarbon is, 3,3-dimethylhexane
