Rotation around carbon-carbon single bond of ethane is not completely free. Justify the statement.

Options

  1. AThe statement is incorrect; rotation around the carbon-carbon single bond in ethane is entirely free.
  2. BThe statement is inaccurate because ethane has a fully single bond character in the C-C single bond.
  3. CThe rotation about C—C bond is restricted because of repulsion between electron cloud of C—H bonds on either c
  4. DThe statement is accurate due to the steric hindrance between the two carbon atoms.

Correct answer

C. The rotation about C—C bond is restricted because of repulsion between electron cloud of C—H bonds on either c

Step-by-step solution

Correct Option is : (C) The rotation about C—C bond is restricted because of repulsion between electron cloud of C—H bonds on either carbon atoms.
