Question

How does changing the electronegativity of the atoms affect the bond character?

Answer 1

With the increase of electronegativity of atom different Bond character are change like bond energy Bond length Bond nature and bond angle

1- with the increase of electronegativity ionic character of atom increases. If atom not attached with the same atom.

2_ with the increase of electronegativity bond energy increases and the bond length decreases

3_ with the increase of electronegativity the bond angle between two Bond increases. Example - bond angle of ammonia is 107 while phosphine is about 93 degree because Phosphorus has less electronegative than nitrogen

4- as the electronegativity of atom increases. Stability of its Negative Ion increases example_ Cl- is more stable than S2-.

With the increase of electronegativity of central atom acidic character of molecule increases. Rule is not applicable in group only applicable in period.
