This transfer of electrons is termed electrovalence in contrast to covalence.In the simplest … Also, the `C-O` bond is more polar than the `C-N` bond due to higher electronegativity difference. $\mathrm{CH}_{3} \mathrm{OH}$b. Molecular compounds are composed of atoms that share electrons, whereas ionic compounds are composed of atoms that transfer electrons due to an electronegative difference. Covalent or molecular compounds contain atoms held together by covalent bonds. CO2 Carbon dioxide These molecular compounds (covalent compounds) result when atoms share, rather than transfer (gain or lose), electrons. Why are Group $1 \mathrm{A}(1)$ and Group $2 \mathrm{A}(2)$ elements found in many compounds, but not Group $8 \mathrm{A}(18)$ elements? Due to the presence of an actual bond, bonds in a molecular compound are directional - towards the nuclei of the atoms. (Note: If the prefix of the first element would be “mono-”, it is not needed.)TIP! Unlike ionic compounds, electrons are not either gained or lost by an atom here. Recall that a molecular formula shows the number of atoms of each element that a molecule contains. Water is one of the most commonly found molecular compounds, followed by carbon dioxide, carbon monoxide, hydrogen peroxide, and methane. 2. Naming Binary Molecular Compounds. Antonyms for Molecular compound. Molecular Compounds. The attraction that occurs between the atoms of molecules is known as a covalent bond.
