Question

what is aliphatic hydrocarbons and aromatic hydrocatbons. explain plz

Answer 1

Aliphatic compounds don't just have to be made of only carbon and hydrogen like hexane, they can also contain atoms like oxygen. Isopropanol is an example of one such compound which contains an alcohol (-OH) group bonded to an aliphatic carbon chain. Notice how we can still classify this compound as being aliphatic since it contains only carbon-carbon single bonds.
Aromatic compounds are similar to aliphatic compounds in the sense that they're both made of carbon, however they are also very different from one another in other ways. An aromatic organic compound is characterized by the fact that they contain both a ring structure and a network of alternating double-single-double-single bonds all around the ring. The most common example of an aromatic compound is benzene.

Answer 2

Answer:

Hydrocarbons. aliphatic hydrocarbons, which consist of linear chains of carbon atoms;aromatic hydrocarbons, which consist of closed rings of carbon atoms.
