In such cases, the actual Lewis structure is regarded as a blend of these contributions and is written: The blending together of these structures is actually aquantummechanical phenomenon calledresonance. At this stage, resonance can be regarded as a blending process that spreads double-bond charact...
Because two equivalent Lewis structures can be written, NO2 is a resonance hybrid in which the N–O bond order is 1.5. More than one non-equivalent structure It sometimes happens that the octet rule can be satisfied by arranging the electrons in different ways. For example, there are ...
* The Lewis dot structure for H2molecule is shown below. Note that each hydrogen gets two electrons after forming the bond. The bond between two hydrogen atoms can be shown as a line, which represents a bond pair of electrons. Note: The bond between two hydrogen atoms is non polar since...
doi:10.1007/978-1-4020-9626-6_10Lewis (1916) is generally considered to have presented the first satisfactory model of the covalent (shared pair) bond based on the cubic atom in 1916. It is important to note that the genesis of the...Springer Netherlands...

This is illustrated for structure 3a in Figure 5, where a single bond critical point (bcp) is located between C and O with a bond density of 0.60 · 102 a.u.. This can be rationalized by the higher (Pauling) electronegativity of N (3.05), O (3.44) and S (2.58) compared to C (...
They are synthesized through the condensation between amines and aldehydes (which are both readily accessible) in presence of a Bronsted or Lewis acid catalyst. Although their stability towards hydrolysis is higher, the presence of strong nucleophiles is still dangerous for the maintenance of their ...
