Use your knowledge of electronegativity to pick out the most polar bond in the list below.


Use your knowledge of electronegativity to pick out the most polar bond in the list below: O-N 0 C-H 0 N-H 0 O-C O-H

Answer

*Out of these, O-H bond is more polar *polar bond A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative *When there is a lot of diffrence between the electronegativity of the atoms, then the bond becomes polar. So higher the electronegativity of one of the atoms bonded in the molecule higher is the polarity of the bond. Electronegativity of given elements O (Oxygen) =3.44 N (nitrogen) =3.04 C (Carbon) =2.55 H (hydrogen) =2.2 The O-H bond have the highest difference in electronegtivity of 1.24 compared to others given, that is O-N =0.4 C-H=0.35 N-H=0.84 O-C=0.89

Based upon these O-H bond is found to be more polar in the list
