The most stable conformation for 1, 2-ethanediol (ethylene glycol) is shown belo

Question

The most stable conformation for 1, 2-ethanediol (ethylene glycol) is shown below. It is the most stable conformation because: (remain and pick a reasonable and logical answer with your chemical smarts) this corresponds to an anti conformation. In general, gauche conformations possess the minimum energy. It is stabilized by intramolecular hydrogen bonding. it is a staggered conformation. it has the highest energy of all the possibilities. The least stable conformation of cyclohexane is the boat. twist boat. chair. half-chair twist chair Which pair of species are both bases in the following reaction? HCN H_2O^-CN H_3O^+ H_2O and CN^- H_3O^+ and H_2O HCN and H_3O^+ HCN and CN^- H_3O^+ and CN^-

Explanation / Answer

Ans 5 . D ) It is a staggered conformation .

The repulsive forces in the molecule affects the stability of the conformation .

In staggered conformation , the electron clouds of carbon hydrogen bonds are as far apart as possible, so that there are minimum repulsive forces . This creates minimum energy and maximum stability of the molecule.
