Q. Among the three conformations of ethane, the order of stability follows the sequence

KEAMKEAM 2012Hydrocarbons

Solution:

The eclipsed conformation is least stable because the hydrogen and bonding pairs of electrons on adjacent carbon atoms are as close to one another as possible. This causes maximum repulsion and least stability. Staggered conformation is most stable because of minimum repulsion. Gauche conformation lie between these two in stability. Thus, order of stability is
staggered > gauche > eclipsed
