It comes into use when atoms cannot gain or lose electrons to achieve the octet configuration. What is a double bond in chemistry? A double bond in chemistry is a type of covalent bond. Two atoms share two pairs of electrons to complete their octet....
We found that the conventional methods for H-bond detection cannot detect all of the H-bonds that are important for the understanding of the reaction mechanism of AhpE involving the cysteine sulfur of the active site. By applying the Non-Covalent Interaction (NCI) method11 previously used to ...

Scientist Pauling introduced the revolutionary concept of hybridization in the year 1931. ...
A Lewis structure is a structural representation of a molecule where dots are used to showelectronpositions around theatomsand lines or dot pairs representcovalent bondsbetween atoms. The purpose of drawing a Lewis dot structure is to identify the lone electron pairs inmoleculesto help determine che...
The phenomenon, though not yet fully understood, is irreversible because a covalent bond in a fluorophore molecule that transits from the singlet state to the triplet state. Some fluorescent materials undergo bleaching as soon as they are excited, while some may experience thousands or millions of ...
