(a) Both A and R are true and R is the correct explanation of A (b) Both A and … WebFluorine is an anomaly. Bond strength decreases from chlorine to iodine as down the group, the atomic size becomes larger and thus the valence electron orbitals become more diffused, causing the overlap of orbitals to become less effective. Therefore the halogen-halogen bond becomes weaker. Fluorine is an exception due to its extremely small size. north middlesex hospital health roster

WebDec 17, 2024 · HF is a weak acid because the bond between H and F is extremely short since F has a very small atomic radius. The shorter a bond is, the stronger the bond is. The stronger bond makes it harder for the HF bond to break when dissolved in H2O causing the acid to be weak. Top.
