Question

What is the name of this hydrocarbon?


3,3–dimethylhexane




4,3–dimethylhexane




4,4–methylhexene




4,4–trimethylhexyne

Answer 1

Then we count the number of substitutents. there are two methyl groups

so it will be di methyl-hexane

but, remember that we must ensure that these groups have the lowest possible number designation too. we also notice that they are at the same carbon too.

the lowest possible number we can give these is 3. because both substituents are at carbon 3.

hence 3,3 di methyl-hexane
