write short note on non polar compounds with methane as an example
Answers
Answer:
area has more negative electric charge, making the opposite side positive. By contrast, a nonpolar molecule has a fairly uniform charge on its outside surface, making no side more negative or positive than another. Both the shape of the molecule and the type of bonds between atoms determine whether it’s polar or not.
Answer:
Covalent compounds in which there is no electronegativity difference are known as non-polar covalent compounds. In these compounds, there is no change of electronegativity such that there is no motion of bond pair of electrons towards the bonded atoms.
Hence, there is no bond or dipole moment between the atoms of a molecule and no development of charges on the atoms further making molecule non-polar and non conducting.
Explanation:
Properties Of Non-polar Covalent Compounds
1. Physical State: These are mainly existing as gases and less existence as liquids
2. Nature: These are very soft in nature.
3. Solubility: These are insoluble in water or less soluble in water. But these are more soluble in non-polar solvents like CCl4, CHCl3 etc.
4. Conductivity: These are insulators since they have no chargeable particles.
5. Boiling And Melting Points: since they don’t have any interaction or polarity they have very low boiling and melting points,
6. Dipole moment: Since the bond is no more polar they have zero dipole moment.
Examples:
The common examples are He, Ne, Ar, Benzene, H2, N2, O2, Cl2, Carbon dioxide, Methane, etc. All these do not show polarity in their bonds instead they show zero dipole moment.
