Question

Among the following bonds, which has the most polar character ?

• A. $C-O$
• B. $C-Br$
• C. $C-F$
• D. $C-S$

Answer 1

Answer: (C)

$C-F$

The bond with the polar character is the one in which there is a high electronegativity difference between the atoms.
We know that Flourine is the most electronegative element. Hence, in this case $C-F$ bond will be the most polar of them all. Hence option C is the right answer.
