which of the following is strongest bond explain with reason S-H, O-H, I-H , F-H Share with your friends Share 0 Vartika Jain answered this Dear Student, H-F bond is the strongest bond.This is because F is the most electronegative element and H is highly electropositive. Also, they both have comparable size, therefore strong ionic bond exists between them. H-O is less stronger than H-F since O is less electronegative than F. Also I and S have larger size and less electronegativity, therefore H-S and H-I bond is also weaker than H-F. 2 View Full Answer Ftft answered this I-H -1 Samik Haldar answered this F-H is the strongest bond as F is more electronegative and H is electro+ve.so F pulls electron and H becomes 'del+ve' and F becomes 'del-ve' 1
