Question

Increasing order of stability among the three main conformations (i.e., Eclipse, Anti, Gauche) of 2-fluoroethanol is : (A) Eclipse, Gauche, Anti (B) Gauche, Eclipse, Anti (C) Eclipse, Anti, Gauche (D) Anti, Gauche, Eclipse

HO —CH2 — CH2—F Gauche conformation is comparatively more stable due to hydrogen linkage in between F and H (at O-atom), hence order is Eclipse, Anti (staggered), Gauche.
