alkanes are called paraffins alkenes are called olefins and benzene as aromatic compound.why?
​

Answer 1

Answer:

Alkenes are known as Olefins because ethylene, which is the first member in the series of alkene also known as ethene was found to yield oily products when they were made to react with chlorine and bromine.

Alkanes have only single bonds which are sigma covalent. ... Hence, alkanes are called paraffins because they have lesser affinity towards general reagents. In other words they are inert, not readily active.

Aromatic hydrocarbons have formulas that can be drawn as cyclic alkenes, making them appear unsaturated, but their structure and properties are generally quite different.
