Less ionic compound among the following
Less ionic compound among the following
Open in App
Solution
The correct option is D NaCl
The decreasing order of ionic character NaF > NaCl > NaBr > NaI.
Because among the halogens the electronegativity is more for Fluorine followed by Chlorine, Bromine, Dodine. According to Fajan's rule, the size should be small to have more ionic character. Thus NaF is more ionic. And NaCl is less ionic .
Hence , option D is correct .
