3 color rule

Compounds containing three elements (ternary compounds), one of which is oxygen are named with suffix ate at the end, provided there is only one such compound. If there are two compounds, the one with more oxygen is named with the suffix ate and the one with less oxygen is named with -ite ending. ..

A doubly or triply bonded atom is considered as two or three atoms. For e.g., if we consider an atom Y ..

If n N, then ..

If two atoms attached to the chiral carbon atom are same, priority cannot be decided according to rule 1. The atoms attached to each of these first atoms need to be compared. For e.g., in sec-butyl chloride consider the methyl group CH 3 . The second atoms attached to the met..

In the first row transition elements all the elements except Zn form colored ions. As these elements have incomplete d-orbital, some amount of energy is required to promote the electrons from lower energy level to higher energy level. This process exhibits radiations from which the compo..

One fourth of the set is to be colored. How many circles would you color? => 1 or 3 or 4..

While writing a unit, only its singular form is used. The abbreviation does not have a full stop. The sign of degree ( o ) is omitted when Kelvin scale is used. Unit combinations should be indicated by means of either a dot or leaving space in between. Metre Kelvin = m.K or m K Words..

The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with Aufbau principle as already discussed for atoms. 2. Each molecular or..
