nh3 octet rule

Exceptions to the Octet Rule - While the octet rule is very useful for describing bonding in a large number of compounds, there are many exceptions to this rule..

Where duplet is formed? A hydrogen atom has only one electron in its valence shell. It needs one more electron to fill its valence shell. The completed shell has the electronic arrangement of the noble gas helium, yet an octet is not completed. However we still get a stable m..

The elements of group 1, 2 and 13 contain less than four electrons in their valence shell. An octet cannot be achieved by electron sharing for these elements. As a result, elements of these groups should not ordinarily form covalent compounds, but some elements do. Boron halides (BF ..

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 ..

. This is a very important rule and is also called the Octet rule. The presence of 8 electrons in the outermost shell makes the atom very stable. Keeping these points in mind let us write the electronic configuration of elemen..

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..
