To explain the abnormality in some molecules , the conecpt of H-bonding was introduced , Hydrogen bonding is defined as the phenomenon in which H-bonding beteen two molecules is called intermolecular H-bonding between two molecules is called intermolecular H-bonding .Hbonding within a molecule is called intramolecular H-bonding or within a molecule is called intramolecular H-bonding or chelation .Intermolecular H-bonding favoure for cluster formation whereas intramolecular H-bnding prevents the cluster formation `HF_2^-` exists in solid state and in liquid `HF` but bot in aqueous solution because :A. `HF_2^- + H_2O rarr H_3 O^+ + 2F^-`B. ` HF+ H_2O rarr H-2 F^+ + OH^-`C. ` HF_2^- +H_2 O rarr H_2 F_2 + OH^-`D. none of these |
