Which compound there is no existence of molecules?

The strong electrostatic attraction between adjacent cations and anions is known as an ionic bond. The most common example of an ionic compound is sodium chloride NaCl, better known as table salt. Unlike covalent compounds, there is no such thing as a molecule of an ionic compound.

Is NaCl a molecule?

As a molecule, NaCl is not considered. Atoms that are bound together by chemical bonds are made up of molecules. Bonding to Covalent. By transferring electrons that generate ions, ionic compounds, such as sodium chloride (NaCl), are produced.

Is CH4 a binary compound?

Binary Ionic Compounds Containing a Metal and a Nonmetal. A binary compound is a compound formed from two different elements. There may or may not be more than one of each element. CH4 Binary, since there are only two types of atoms. CHCl3 Not binary or diatomic.

Why ionic compounds are not molecules?

No, ionic compounds are crystals of infinite cations and anions bound together. There is no “molecule” of ionic compounds such as, for example, NaCl, because there are no single units of the compound.

Which molecule does not exist b2?

Be2 molecule
The electronic configuration of Beryllium is 1s2 2s2. From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium. Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.
