States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Explanation
Absolute configuration (R and S nomenclature)
- It is applicable for any molecule and any stereo chemical formula
- It was first reported Chon, Ingold, Prolag, and simply denoted as a C.I.Ps rules
- It is assign the priority of group to the asymmetric centre and based on some rules are called c.i.p rules
- 1,2,3 priority groups are arranged in clock wise direction called “R” (rector) configuration
- 1,2,3 priority groups are arranged in anticlock wise direction called “S” (senster) configuration
- But in fisher projection formula least priority group is present on horizontal line then the above configuration is inverted.
- First you’ve correctly identified the chiral centre in your molecule that is the first step. When doing work with chiral centres, it is very essential to use solid lines to represent bonds in the plane of the screen, bold wedges to represent bonds coming from the plane of the screen towards the viewer and dashed wedges to represent bonds from the plane of the screen away from the viewer.
