2005 · Q125

NEETChemistryChemical Bonding and Molecular StructureMCQ+4 / −1
The correct sequence of increasing covalent character is represented by
  1. A
    LiCl < NaCl < BeCl2
  2. B
    BeCl2 < LiCl < NaCl
  3. C
    NaCl < LiCl < BeCl2
  4. D
    BeCl2 < NaCl < LiCl
View written solutionFree

Correct answer: C

As difference of electronegativity increases % iconic charecter increases and covalent charecter decreases i.e, electronegativity difference decreases covalent charecter increases. Further greater the charge on the cation more will be its covalent character. Be has maximum (+2) charge.
