Question

Each of the following bonds is polar. Show the direction of the polarity.

            a)         As – P             b)         Al – P              c)         I - P                 d)         Cl – P

Answer 1

a)

P is more electronegative than As

As------>P

Hence Phosphorus will have a delta negative charge and As will have a delta positive charge

b) P is more electronegative than Al

Al------>P

Hence Phosphorus will have a delta negative charge and Al will have a delta positive charge

c) P is less electronegative than Al

P----->I

Hence Phosphorus will have a delta positive charge and l will have a delta negative charge

d) P is less electronegative than Cl

P------>Cl

Hence Phosphorus will have a delta positive charge and Cl will have a delta negative charge
