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).
True. An aromatic compound, no matter how bad it is for us, will ALWAYS smell nice and fragrant.

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
A biphenylene is a tricyclic aromatic hydrocarbon formed from two benzene rings joined by two adjacent single bonds, or any derivative of this compound.
C8H18 is indeed an organic molecule. It is an aliphatic compound, meaning it is composed of carbon hydrogen and it is not aromatic.
Aromatics contain a six-member ring, in which the majority of the atoms are (usually) carbon, where the bonds between adjacent atoms alternate as single-covalent and double-covalent. Cycloalkanes contain only single-covalent bonds, and can refer to any size ring.
i don't have any idea
You think probable to a chemical compound. But today the theory of the fixed composition is not generally valid.
Assuming you mean organic chemistry : An unsaturated compound is any chemical compound containing one or more double or triple bonds or pi-clouds (eg aromatic compounds). Examples are : ethylene Acetylene benzene cyclopentadiene There are thousands of them - the definition gives you the set. Work it out from there.
Huckels rule. 4n + 2 whereby n is any integer for example 1,2,3 etc. Aromatic compounds will obey huckels rule:- (4 x (1)) + 2 = 6 (4 x (2)) + 2 = 10 (4 x (3)) + 2 = 14 Taking benzene as an example...is it aromatic? Is a six membered ring with 3 double bonds, so 6pi electrons thus obeys huckels rule and is aromatic. Negative charges also count as 2pi electrons and positive charges on a molecule are ignored entirely.
If you understand by substance a chemical compound this is not a mixture.If you understand by substance any material this is homogeneous when only one phase exist.
