Gauche (skew) form

Vedclass · Answer

(C) In ethylene glycol $(HO-CH_2-CH_2-OH)$,the most stable conformation is the $Gauche$ (skew) form. This is due to the formation of an intramolecular hydrogen bond between the hydroxyl groups,which stabilizes the $Gauche$ conformation. Although the $Staggered$ form minimizes steric repulsion,the energy gain from the intramolecular hydrogen bond in the $Gauche$ form makes it more stable.
