Compounds covalent bonds

The valence-bond concept of orbital hybridization described in the previous four sections is not limited to carbon compounds. Covalent bonds formed by-other elements can also be described using hybrid orbitals. Look, for instance, at the nitrogen atom in methylamine, CH3NH2, an organic derivative of ammonia (NH3) and the substance responsible for the odor of rotting fish.

In certain organic compounds, covalent bonds can be so strongly polarized that their structure and reactivity may be approximated by the corresponding ionic formulas. For example, the covalent bonds in methyl triflate 48 and methyllithium 49 are so strongly polarized that they behave as if they were fully ionized compounds, sources of the methyl cation and methyl anion respectively ... 

With simple organic compounds covalent bonds result from the combination of the four unpaired electrons in the sp -hybridized orbitals of carbon with the impaired electrons of hydrogen or oxygen. 

Chemical bond An attraction between atoms or ions in chemical compounds. Covalent bonds and ionic bonds are examples. 

When electrons are shared rather than transferred, the shared electron pair is referred to as a covalent bond. Compounds characterized by covalent bonding are called covalent compounds. Covalent bonds tend to form between atoms with similar tendencies to gain or lose electrons. The most obvious examples are the diatomic molecules Hj, Nj, Oj, Fj, Clj, Brj, and Ij. Bonding in these molecules is totally covalent because there can be no net tendency for electron transfer between identical atoms. The formation of Fj, for example, may be represented as...

In a molecular compound, covalent bonding happens when two nonmetals share electrons. Covalent bonds are defined not only by the number of electrons shared but also by their length and strength. Covalent bonds have a specific bond length and bond energy. In a homonuclear diatomic molecule where both atoms are identical, the pair or pairs of electrons is/are shared equally between the two atoms. However, in a heteronuclear diatomic molecule, one shared pair(s) will be more attracted to one atom than the other.
