It means, that the distance between the same pair of atoms (e.g., C-H) may vary depending on which compound we are dealing with. 8. %���� <> 141 pm C. 109 pm D. 73 pm E. 35 pm However, the hydrogen bond strength in supercooled liquid water may be stronger than in ice [2020]. So, using both the Valence Shell Electron Pair Repulsion (VSEPR) Theory and the table where we look at the AXN, we can quickly know about the molecular geometry for water. Hence, I − I has the highest bond length. Looking at the table, when we go from AX2, AX3 and all the way down to AX2N2, we will find out that the bond … Given that the atomic radii of H and I are 25.0 and 133 picometers, respectively.

In a hydrogen bond, the electronegative atom not covalently attached to the hydrogen is named proton acceptor, whereas the one covalently bound to the hydrogen is named the proton donor. Hence, option A is correct. Constants For Water.
