gauche

Vedclass · Answer

(B) In ethylene glycol $(HO-CH_2-CH_2-OH)$,the gauche conformation is the most stable.This is due to the formation of an intramolecular hydrogen bond between the two hydroxyl $(-OH)$ groups,which stabilizes the gauche form.Although the anti conformation minimizes steric repulsion,the stabilizing effect of the intramolecular hydrogen bond in the gauche conformation makes it more stable.
