What is the name of this hydrocarbon?

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
