Other articles where covalent compound is discussed: amide: The covalent amides are neutral or very weakly acidic substances formed by replacement of the hydroxyl group (OH) of an acid by an amino group (NR2, in which R may represent a hydrogen atom or a
In a Lewis structure of a covalent compound, the shared electron pair between the hydrogen and chlorine ions is represented by a line. The electron pair is called a bonding pair; the three other pairs of electrons on the chlorine atom are called lone pairs and play no direct role in holdin...
Covalency :The number of electrons contributed by the atom of an element in the formation of covalent compound is known as covalency of that element. In Lewis dot model, the electrons in the valence shell of the atom are shown as dots around it. ...

As we noted earlier, a covalent bond is drawn as a dash in aLewis structure. Also, in a Lewis structure, nonbonding electron pairs are shown as “dots.” TheLewis structuresof four simple organic compounds: methane,aminomethane, methanol, andchloromethaneare shown below with both bonding and...
However, further experiments showed that the compound is cellularly impenetrable due to two negative charges on the phosphate, which lead to a modified structure (SML-10-70-1) [86]. The warheads of both inhibitors are α-chloroacetamide. The use of α-chloroacetamides or α-haloacetamides sh...
A coordinate covalent bond is a bond between two atoms in which one atom donates a lone pair of electrons to form the bond. Coordinate covalent bonds are closely related to Lewis acid/base theory, in which an electron donor (Lewis base) donates a lone pair of electrons to an electron acce...
8.1 Formulas of Some Molecular Compounds Molecular Formulas The formula of a molecular compound indicates the numbers and kinds of atoms. The arrangement of the atoms within a molecule is called its molecular structure. Using Models Which of these molecules has the greatest number of oxygen atoms?
How can a molecular compound have polar bonds but an overall polarity of a non-polar compound, for example BeCl2? What are the bond angles for these compounds? Water Ammonia Methane But-2-ene Propan-2-ol Why do chemical properties depend on electrons?
