In general terms, aroma denotes odor that distinguishes different 
compounds. However, aromatic chemistry defines the compounds in 
organic chemistry area with particular chemical, structural and 
electronic properties.
What are aromatic hydrocarbons ?
Aromatic hydrocarbons are unsaturated cyclic groups of hydrocarbons 
with one or more planar six-carbon rings having delocalized electrons. 
These hydrocarbons are mainly made up of hydrogen and carbon 
atoms. These circularly structured compounds contain sigma bonds 
with delocalized pi electrons which lead to increased stability. These 
are also called aryl hydrocarbons or arenes. These compounds have 
different unique characteristics that distinguish those from other 
organic compounds.
In aromatic hydrocarbons, the carbon atoms have double bonds in the alternating 
rings. The atoms can share their valance electrons in the delocalisation process. 
As a result, it creates more stable molecules and generates several properties that 
turn them important for humans. One of the most crucial properties of aromatic 
hydrocarbons is the capability to subsist in several resonance structures. The 
resonance structures arise when the bonds get arranged in multiple ways and 
direct the delocalization of valance electrons. Resonance helps in creating more 
stable molecules which are less reactive than molecules experiencing no 
resonance. This property is important for hydrocarbons as it allows them to 
interact with other molecules without changing their chemical composition.

Another important property is having a high carbon-to-hydrogen atom ratio. The 
valence electrons get delocalized across double bonds as a result the number of 
carbon atoms in the hydrocarbon remains higher in comparison to the hydrogen 
atoms. The aromatic hydrocarbons are non-polar owing to their composition of 
hydrogen, aromatic structure, and carbon atoms. For this property, they don’t mix 
with water and can’t be used as solvents for other non-polar molecules.
The first recognized hydrocarbon is benzene. Pyrimidines, toluene, purines, etc 
are some examples of aromatic hydrocarbons. The aromatic hydrocarbons are 
divided broadly into two categories- benzenoids and non-benzenoids. The 
compounds consisting of at least one benzene ring are benzenoids, while the 
compounds without benzene rings are non-benzenoids. Major of the compounds 
is under benzenoids as most of those retain benzene rings even after undergoing 
several chemical reactions.
Applications of aromatic chemistry
The contribution of aromatic chemistry is pivotal which improves life quality in 
everyday life. Aromatic hydrocarbons are common in synthetic as well as 
biological processes. Its uses are completely dependent on the properties.
 The most important usage of aromatic hydrocarbons is as a non-polar solvent 
for other molecules. Aromatic hydrocarbons have multiple uses including as 
paints, gasoline, additives in lacquers and many other purposes. The low 
reactivity feature of the hydrocarbons also supports those to get used as 
solvents.
 Aromatics play a crucial role in the pharmaceutical industry. Some particular 
aromatics resins are used for drug purification. 
 This aids in the extraction of the therapeutic components and the organic 
impurities. These technologies and resins have been used in antibiotics as 
well as in the development of therapies including AIDS, arthritis, and 
different forms of cancer.
 Aromatics are extensively used in the automotive industry. Different parts of 
vehicles are made from products that are derived from aromatics. The 
products derived from aromatics meet various demands of modern motorists 
who desire cars with high performance, improved safety, style, reliability, 
and competitive pricing. Moreover, it reduces the environmental impact of 
driving drastically.
 Aromatics are also extensively used in the sports equipment manufacturing 
industry. The aromatic-derived products are lightweight and high performing. 
These have replaced the traditionally-used leather and wood. From sports 
shoes and football to rackets; aromatic-derived products are used as the best 
alternatives for manufacturing these sports equipment.
 Aromatics are widely used in the building and construction industry. From 
insulation, window frames, and piping to interior designs, the products 
derived from aromatics have an extensive contribution to making our 
Improved Decision Making – Brain scans of different individuals show that 
most brains are overworked, with hardly any rest days in between. Therefore, 
there is no time to restore and regenerate, which creates confusion in the mind. 
Silence improves rest time, in which the brain can function properly, thus helping 
i n making solid decisions.
Tips to Incorporate Silence Routines in Daily Schedule
The best way to relax is to meditate for about 20 minutes when you switch off 
your brain and stop doing activities. However, many people do not find it 
feasible. Thus, for them, small 5-minute gap sessions and even nap sessions of 15 
minutes can work wonders where your mind turns off and relaxes and rejuvenates 
every day by listening to the inner voice.
