Question

In n-butane fully eclipsed conformation
has highest energy due to presence of
interaction between ...​

Answer 1

Answer:

Correct option is

B

steric strain only

Fully eclipsed form of n-butane has 2 methyl groups at the back of each other, making it least stable due to steric strain.

Answer 2

In n-butane fully eclipsed conformation has highest energy due to presence of interaction between two methyl groups.

CONFORMATION:

• Conformations are way to describe the geometry or shape of molecule.
• There are different type of conformations like newmann,sawhorse etc.
• In sawhorse and newmann,there are eclipsed and staggered conformations.
• In n-butane,eclipsed conformation is the least stable one.
• The eclipsed conformation has the highest energy because of the interaction between two bulky methyl groups.
