Question

in a hydrocarbon 6 carbon atoms are present 2nd and 4th carbon atom contain one CH3 group give the name of hydrocarbon​

Answer 1

Answer: 2,4-dimethylhexane

Explanation: Hydrocarbons are the organic compounds containing Carbon and Hydrogen . They may be alkane , alkene , alkyne or aromatic hydrocarbons .

Alkanes contain single bond between two carbon atoms . IUPAC suffix : ane

Alkenes contain double bond between any two carbon atoms . IUPAC suffix : ene

Alkyne contain triple bond between any two carbon atoms . IUPAC suffix : yne

Aromatic compounds contain at least one benzene ring in them .

Since in the question , it is not mentioned what type of hydrocarbon the compound is , we take for convenience let it be an alkane . We have next that it contains 2 methyl groups (dimethyl) at position 2 and 4 . So the IUPAC name of our compound is 2,4- dimethylhexane .
