Vesper, per se, can be many diffrent things. However, 'A' vesper most likely refer to a drink, created by Ivar Bryce and mentioned in Bryce's friend Ian Fleming's books about super-spy James Bond, and made famous in the recent Bond movie Quantum of Solace.
A polar covalent bond is a bond between two nonmetal atoms with different electronegativity's. Technically, only a bond between identical nonmetal atoms would be truly nonpolar, but in most cases a threshold is set for electronegativity difference to be considered polar.
H2 molecule is the least polar. Between H2O and H2S, the most polar will be H2O as oxygen is more electronegative than sulphur.
A covalent bond is most likely to be polar when there is a large difference in the electronegativity of the two atoms that form the bond.
Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.
In a polar covalent bond, they spend more time closer to the more electronegative atom. In a non polar bond the spend their time mainly between the atoms showing no "favouritism"
a non-polar covalent bond
Check the electronegativities of the atoms in the bond. The bond will be polar if there is a difference in electronegativity. The most electronegative element will attract the bonding eletrons to it becoming slightly negatively charged. The other end of the bond will become slightly positively charged. For example a bond between carbon and chlorine, C-Cl: C electronegativity 2.55 Cl electronegativity 3.16 The bond will be polar because of the difference in electronegativity, and Cl will be slightly negative, carbon slightly positive.
A good candidate would be the bond in HF.
A covalent bond. Non-polar covalent is stronger than polar covalent as well.
NO, hydroxyl group is more polar than methyl group due to the electronegativity difference between atoms in a bond, the more polar the bond. Partial negative charges are found on the most electronegative atoms
Hydrogen and Fluorine form the most polar bond H-F, the difference of electronegativities is 1.9.
The bond between Boron (b) and AT can be considered as the least polar bond. This is because they both carry an electromagnetic value of 2 and 2.2 respectively thus a small difference of 0.2 EN in between.
