A Quote by Otto Wallach
In bitter almond oil, like in a great number of other substances that previously had been counted among the 'aromatic compounds' on behalf of their strong smell, a derivative of benzene is present. The special properties of benzene and its derivatives are caused by the typical arrangement of their carbon atoms.

At night, I'll do coconut oil or almond oil on my face as a mask to replenish my skin. I've found those are so simple but work better than any other product. Coconut oil is so good, but if you don't want to smell like a cookie, sweet almond oil isn't as pungent.
Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.
The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.
The number of the fixed stars which observers have been able to see without artificial powers of sight up to this day can be counted. It is therefore decidedly a great feat to add to their number, and to set distinctly before the eyes other stars in myriads, which have never been seen before, and which surpass the old, previously known stars in number more than ten times.
Carbon-carbon bond formation reactions employing organoboron compounds and organic electrophiles have recently been recognized as powerful tools for the construction of new organic compounds.
Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.
I would trade all my experimental works for the single idea of the benzene theory.
Organic compounds exist in which a hydrogen atom, joined to the carbon, acquires acid properties as a result of the proximity of certain functional groupings.
Are the atoms of the dextroacid (tartaric) grouped in the spirals of a right-hand helix or situated at the angles of an irregular tetrahedron, or arranged in such or such particular unsymmetrical fashion? We are unable to reply to these questions. But there can be no reason for doubting that the grouping of the atoms has an unsymmetrical arrangement with a non-superimposable image. It is not less certain that the atoms of the laevo-acid realize precisely an unsymmetrical arrangement of the inverse of the above.
E-cigarettes contain many harmful chemicals that tobacco cigarettes do not contain such as formaldehyde, benzene, propylene glycol, and metals like cadmium, nickel, and tin.
I was working with these very long-chain ... extended-chain polymers, where you had a lot of benzene rings in them. ... Transforming a polymer solution from a liquid to a fiber requires a process called spinning. ... We spun it and it spun beautifully. It [Kevlar] was very strong and very stiff-unlike anything we had made before. I knew that I had made a discovery. I didn't shout "Eureka!" but I was very excited, as was the whole laboratory excited, and management was excited, because we were looking for something new. Something different. And this was it.
In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely.
Chemical compounds of carbon can exist in an infinite variety of compositions, forms and sizes. The naturally occurring organic substances are the basis of all life on Earth, and their science at the molecular level defines a fundamental language of that life.
The emitters of the spectral series are without exception single atoms, not compounds of atoms.
Physiology is the science which treats of the properties of organic bodies, animal and vegetable, of the phenomena they present, and of the laws which govern their actions. Inorganic substances are the objects of other sciences, - physics and chemistry.
If you own a chemical plant and leak a little benzene, you're in big trouble because everyone knows how carcinogenic it is. But coming out of a tailpipe? The government never does anything about that.
