In: Chemistry
Rank the following in order of increasing polarity: CH3CI, CH3F, and CH3Br
(Please input answers with the following format: CH3CI)
Least polar
Most polar
Given compounds CH3Cl , CH3F , CH3Br.
If the electronegativity difference of bonded atoms is more, bond polarity is more.
Order of electronegativity of F, Cl, Br is F > Cl > Br
Hence,
electronegativity difference order of bonds is C-F > C-Cl > C-Br
Then,
Bond polarity order is C-F > C-Cl > C-Br
Therefore,
Bond polarity order of given compounds is CH3F > CH3Cl > CH3Br
--------------------------------------
least polar = CH3Br
most polar = CH3F
