Define the general formula of non-polar compound on the basis of given information, where the electronic configuration of valence shell for A and B are as follows (a) ns^(2)np^(3) (b) ns^(2)np^(5): (P) AB_(3) (Q) AB_(4) (R) AB_(5) (S) AB_(6)^(-)

Answer»

<P>P,Q,R
Q,R,S
R,S,P
S,P,Q

Solution :`AB_(5)` has ONE lone PAIR at (A), so it will be polar.
