Organic Chemistry Basics - Result Question 40
46.
(a) Draw Newman’s projection for the more stable staggered form of butane.
(b) Relatively less stability of the staggered form is due to the higher potential energy of the staggered conformation compared to the more stable eclipsed or staggered forms.
(i) Torsional strain
(ii) van der Waals’ strain
(iii) Combination of the two above
(2004, 5M)
Show Answer
Solution:
less stable staggered conformation of butane
(b) The less stability of above mentioned conformer is due to van der Waals’ repulsion between the adjacent methyl groups.
