Question
Increasing order of stability among the three main conformations (i.e. Eclipse, Anti, Gauche) of $2-$ fluoroethanol is
✓
Answer
a
Gauche conformation is comparatively more stable due to hydrogen linkage in between $\mathrm{F}$ and $\mathrm{H}(\mathrm{atO}-$ atom), hence order is Eclipse, Anti (staggered), Gauche.
