MOLECULAR POLARITYFIELD NOTE 22 / 175
Is C2H5F polar or nonpolar?
Fluoroethane (C2H5F) is polar because its terminal C–F bond creates a distinct fluorine-rich end.

Why C2H5F is polar
Fluoroethane is an ethane skeleton with one H replaced by F. Both carbons remain locally tetrahedral, but the strongly polarized C–F connection gives the molecule an uneven charge distribution.
What to notice
Ethane and fluoroethane have similar carbon frameworks; the fluorine substitution makes their polarity classification different.
