MOLECULAR POLARITYFIELD NOTE 23 / 175
Is C2H5I polar or nonpolar?
Iodoethane (C2H5I) is polar because the C–I substituted end is chemically different from the methyl end.

Why C2H5I is polar
Iodoethane has a terminal iodine atom bonded to a tetrahedral carbon. The substituted end differs from the opposite CH3 end, yielding a molecular dipole despite iodine being less electronegative than fluorine.
What to notice
A C–I bond is less strongly polarized than a C–F bond; the presence of a halogen alone does not tell you the dipole magnitude.
Common questions about C2H5I
