Q.30 Ionic character of the covalent bonds in the compounds Cl₂, HCl, NaCl, NaF follows the order
Ionic character of the covalent bonds in the compounds Cl₂, HCl, NaCl, NaF follows the order
(A) Cl₂ > NaCl > HCl > NaF
(B) HCl > Cl₂ > NaF > NaCl
(C) HCl > NaCl > NaF > Cl₂
(D) NaF > NaCl > HCl > Cl₂
Answer
Answer: (D) NaF > NaCl > HCl > Cl₂
Explanation: Ionic character increases with the difference in electronegativity. NaF has the highest ionic character, followed by NaCl, HCl, and Cl₂.
