Question

Which kind of bonds is a polar substance more likely to have than a nonpolar substance?
Choose the letter choice that combines your choices.
            1- H-Cl
            2- H-C
            3- H-O

		1, 2, and 3
		1, 2
		1, 3
		2, 3
		none of these combinations

Answer 1

Amongs the following option

1. H-Cl (hydrogen & chlorine)

2. H-C. (Hydrogen & carbon)

3. H-O. (Hydrogen &oxygen )

Now , from the following options , we have to found which kind of bond is polar substance and which is non-polar . So , in H-Cl , the electronegative difference is 0.9 (approx) , in H-C , the electronegative difference is 0.35 , whereas, in H-O, the electronegative difference is 1.34 which is maximum in this . As , oxygen and chlorine are electronegative atoms that's why we can see such major difference in electronegativity which in turn increase their polarity . So, according to question : 1,3 combination are polar substance which is H-Cl and H-O.
