Which of the following molecules, based on the elements present, would be most polar?
|
HF
|
|
H2
|
|
HCl
|
|
HBr
|
Explanation:
Detailed explanation-1: -Hence, among F, Cl and Br, Fluorine is the most electronegative which makes the H-F bond the most polar since fluorine is able to pull the electron density toward itself more.
Detailed explanation-2: -The above discussion suggests that the highest electronegative difference is in the HF molecule, which is 1.78. Therefore the bond between H-F is most polar.
Detailed explanation-3: -The order of polarity is as follows: HF>HCl>HBr>HI.
Detailed explanation-4: -HF is the most polar because F is the most electronegative.
Detailed explanation-5: -In HF, there is a much difference in the electronegativities of hydrogen and fluorine. Therefore (HF) is a polar compound.
