Because,
In alkenes&alkynes,there exists atleast One double bond(pi bond) which is relatively weaker than sigma bond(There are no pi bonds in alkanes.Hence they are saturated).Hence they are unsaturated.
Aromatic compounds are neither saturated nor unsaturated they show dual behaviour, but due to absence of localized pi bonds they usually do not undergo the addition reactions but some addition reactions as Photochemical halogenation and catalytic hydrogenation are also known,.
becouse they contain alternet single and double bond.
Alkenes and alkynes are called unsaturated because they have other than single bonds within their structure. Alkenes have a double bond and alkynes have a triple bond.
unsaturated
hydrocarbons, in general.
aromatic diazo compounds are stabilize by resonance where as in alifati it is not found
They are saturated compounds
No. it is an unsaturated (aromatic) compound.
The aromatic compounds or benzene is mostly found in plant and tree oils. The compound is gathered by coal distillation.
No one hydrocarbon is ionic, saturated , unsaturated and aromatic all hydrocarbons are covalent compounds.
when aromatic compounds were first discovered they were called aromatic due to their plesant odours but as you have rightly pointed out compouns such as diatomic hydrogen have pleasant smells its is becuase of this that the meaning of aromaticity changed as aromatic compounds are saturated stable compounds its the notion of delocalised electrons that defines a aromatic compound now as this enhances the stabilty of the compound so chemically aromatic and aromatic are not particularly synoynymous any more in fact chemical aromacity has very little to do with aromacity and ewhat it does to the oliafactory centres that gives us the perception of smell

Why aromatic compounds have high chemical shift valure?
They are saturated compounds
aromatic diazo compounds are stabilize by resonance where as in alifati it is not found
Not all the anti aromatic compounds have the unpaired electrons, for example cycloocta tetraene
It is false; aromatic compounds is a category of organic compounds with specific odor or color.But many other chemicals have a specific odor or color but they are not aromatic compounds (of course, in the chemical sense).
