How are non polar covalent bonds formed?
1 Answer
Actually, all covalent bonds between different atoms are polar to some extent......
Explanation:
Polarity in covalent bonds can be gauged by comparing electronegativity of each atom. The greater the difference, the more polar the bond. This is because more electronegative atoms tend to pull electron charge density towards themselves, creating a partial negative charge (and therefore a partial positive charge on the other atom).
Therefore, for binary compounds in order to have a truly non-polar covalent bond the two atoms should be identical. Therefore, the bonds in such things as
For more complex molecules, the degree of polarity in a bond will be influenced by the nature of the groups bonded to each atom. Therefore in methanol,
To complicate things further, symmetry plays a part too. Therefore, whilst the bond between carbon and oxygen in
All clear now ? LOL
