1.	Increasing order of stability among the three main conformations (i.e. , eclipse, anti, gauche ) of 2-fluoroethanol is
Answer» eclipse, anti, gauche anti,gauche, eclipse eclipse, gauche , anti gauche, eclipse , anti Solution :Because of intramolecular H-bonding , gauche CONFORMATION of 2-fluoroethanol is more STABLE than anti while ecliped conformation is the least stable. THUS, the increasing ORDER of stability is : Thus, OPTION (a) is correct.
