Dihedral angle between two methyl groups of nn-butane in the gauche and anti forms areDihedral angle between two methyl groups of n -butane in the gauche and anti forms are

Options

  1. A60∘,0∘60^{\circ}, 0^{\circ}
  2. B0∘,60∘0^{\circ}, 60^{\circ}
  3. C60∘,180∘60^{\circ}, 180^{\circ}
  4. D180∘,60∘180^{\circ}, 60^{\circ}

Correct answer

C. 60∘,180∘60^{\circ}, 180^{\circ}

Step-by-step solution

Dihedral angle between two methyl groups of n -butane in the gauche and anti forms are (The angle between C−C\mathrm{C}-\mathrm{C} and C−H\mathrm{C}-\mathrm{H} bonds on adjacent carbon atoms in any conformation is called dihedral angle.) Hence, the dihedral angle in case of gauche is 60∘60^{\circ} and in anti form is 180∘180^{\circ}.
