Conformations in Organic Chemistry

Single bonds have an absolute privilege and exclusivity to show bond rotations, a prime reason behind various conformations in organic chemistry. Conformations are various interconvertible arrangements, or shapes molecules adopt due to their flexibility to undergo bond rotations. The molecules' identity remain the same throughout these rotations. Conformational isomers are covered extensively under the branch of stereochemistry that considers molecular shapes and studies their reactions.

Conformation in Organic Chemistry

The different spatial arrangements organic molecules adopt due to the rotation of the single bond are called conformations. A specific conformation is called a conformer or conformational isomer. Conformations can be formed by open-chain (acyclic) or closed-chain (cyclic) carbon compounds. Examples of some common conformations adopted by carbon-carbon single bonds containing organic molecules are- eclipsed, staggered, gauche, planar, boat, and chair conformations.

Discovery of Isomerism

Discovery of Isomerism occurred around the period when the faith in vitalism, a belief that organic molecules must only come from living organisms, was dwindling. It was J.J. Berzelius, Wohler’s Swedish teacher, who recognized such molecules in 1831-32 and named them isomers (Isomerisk in Swedish for equal parts).

Order of +I Inductive effect

The +I effect is an electron-donating inductive effect shown by an atom or group of atoms relative to Hydrogen. The +I effect of some of the alkyl group of atoms in the decreasing order to Hydrogen is given in the video.

What is an allyl group and allyl position?

An allyl group is three-carbon substituted propene, also called a propenyl group (prop-2-en-1-yl). It has a structural formula CH2=CH-CH2-X, where the X can be an alkyl/aryl group or a functional group.

Role of Physical Properties in Organic Chemistry

Unlike the destructive nature of chemical reactions, the study of physical property is a non-destructive process. Their studies allow us to understand the innate nature of molecules, such as their ability to exist in different states, that is, solid, liquid, or gas, their melting, freezing, or combustion points, or even the angle at which they bend light. These studies don't change the molecular structure but reveal the molecular nature through observation.

Difference between Organic and Inorganic Chemistry

Around the 1780s, chemists began classifying compounds based on their source. In those days, any compound obtained directly or indirectly from living things like plants or animals was called an organic compound. With the downfall of the Vital Force Theory, the term organic underwent changes. We now consider organic compounds to be made of only carbon and hydrogen atoms, collectively called hydrocarbons. All other organic compounds are said to be derived from these hydrocarbons by replacing one or more hydrogen atoms with other atoms or groups.

The average size of an atom

The World is a kingdom of the minuscule! To truly grasp the minuteness of an atom, let’s imagine the tiniest poppy seed that is still visible to the naked eye. If a poppy seed is 1 millimeter long, dividing it into 1000 parts gives a micron. One micron is the size of an invisible bacterium, E. coli. To see such a small size, a 1000X magnification is needed. When microscopic E. Coli is further divided into 1 million (1000000) parts, we arrive at the size of an average atom.
