Statement I: Staggered conformation of ethane is more stable than the eclipsed conformation. Statement II: The torsional strain in staggered conformation is more. Read the above statements and choose the correct answer from the options given below.

Options

  1. ABoth Statement I and Statement II are false
  2. BBoth Statement I and Statement II are true
  3. CStatement I is true but Statement II is false
  4. DStatement I is false but Statement II is true

Correct answer

C. Statement I is true but Statement II is false

Step-by-step solution

Statement I is true because in the staggered conformation of ethane, the electron clouds of the C-H bonds on adjacent carbon atoms are as far apart as possible. This minimizes the repulsive forces between them, making the staggered conformation more stable than the eclipsed conformation. Statement II is false because torsional strain arises from the repulsive interaction between the electron clouds of adjacent bonds. In the staggered conformation, this repulsion is at a minimum, so the torsional strain is minimum,
