The correct statement regarding the comparison of staggered and eclipsed conformations of ethane, is
A
the eclipsed conformation of ethane is more stable than staggered conformation even through the eclipsed conformation has torsional strain
B
the staggered conformation of ethane is more stable than eclipsed conformation, because staggered conformation has no torsional strain
C
the staggered conformation of ethane is less stable than eclipsed conformation, because staggered conformation has torsional strain
D
the eclipsed conformation of ethane is more stable than stggered conformation, because eclipsed conformation has no torsional strain.

The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha-carbon, is
A
a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation
B
a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as keto-enol tautomerism
C
a carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol
D
a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration.
