If the electronegativities of H , N , P , As , Sb are 2.1 , 3 , 2.1 , 2 , 1.9 then arrange in order of decreasing polarity of bonds in SbH 3 , AsH 3 , PH 3 and NH 3 .

If the electronegativities of H , N , P , As , Sb are 2.1 , 3 , 2.1 , 2 , 1.9 then arrange in order of decreasing polarity of bonds in SbH, AsH3 , PHand NH3 .

The corect answer to the question is NH3 > SbH3 > AsH3 > PH3
The polarity of a bond can rougly be said as directly proportional to the difference in electronegativity between the two species in the molecule.
Here I have arranged the order on the basis of magnitude of difference of electronegativity in the given molecules
 
I hope it Helps!!
