Vedclass · Answer

(A) In $2-$fluoroethanol,the Gauche conformation is unexpectedly more stable than the Anti conformation due to the formation of an intramolecular hydrogen bond between the fluorine atom $(F^{\delta -})$ and the hydroxyl hydrogen atom $(H^{\delta +})$.The Eclipse conformation is the least stable due to high torsional strain and steric repulsion.Therefore,the increasing order of stability is: $Eclipse < Anti < Gauche$.

The increasing order of stability among the three main conformations (i.e.,Eclipse,Anti,Gauche) of $2-$fluoroethanol is:
