Which of the following is the correct order of stability of conformations for NH 2 - CH 2 - CH 2 - OH .

Question

TestHub · Accepted Answer

The anti conformation is most stable in which ${NH}_{2}$ and $OH$ groups are far apart as possible and minimum repulsion between two groups occurs.

In fully eclipsed conformation ${NH}_{2}$ and $OH$ groups are so close that the steric strain is maximum.

Since, gauche form is stabilised by intermolecular hydrogen bonding, hence it is more stable than anti.
