Question

Which of the following will have the maximum dipole moment? (A) CH3F  (B) CH3Cl  (C) CH3Br  (D) CH3I

Tardigrade Admin · Accepted Answer

CH3Cl has higher dipole moment than CH3F due to much longer C-Cl bond length than the C-F bond. The much longer bond length of the C-C bond outweighs the effect produced by lower electronegativity of Cl than that of F.

Q. Which of the following will have the maximum dipole moment?

$C H_{3} F$

$C H_{3} Cl$

$C H_{3} B r$

$C H_{3} I$

$C H_{3} Cl$ has higher dipole moment than $C H_{3} F$ due to much longer $C - Cl$ bond length than the $C - F$ bond. The much longer bond length of the $C - C$ bond outweighs the effect produced by lower electronegativity of $Cl$ than that of $F$ .

Q. Which of the following will have the maximum dipole moment?

CH3​F

CH3​Cl

CH3​Br

CH3​I

CH3​Cl has higher dipole moment than CH3​F due to much longer C−Cl bond length than the C−F bond. The much longer bond length of the C−C bond outweighs the effect produced by lower electronegativity of Cl than that of F.

$C H_{3} F$

$C H_{3} Cl$
