Question

draw newman and sawhorse projectionsof various confermations of ethane.compare the stabilities of these conformations giving reasons







​

Answer 1

Explanation:

There are minimum repulsive forces, minimum energy and maximum stability in the staggered form of ethane. Here, the electrons clouds of carbon-hydrogen bonds are as far as possible.

(ii) the electron clouds come closer when the staggered form changes to the eclipsed form. It results in increased electron cloud repulsions. Here, molecules will have more energy and lesser stability.

Therefore, the staggered form is more

Answer 2

Answer:

Stability of conformation:

(i) There are minimum repulsive forces, minimum energy and maximum stability in the staggered form of ethane. Here, the electrons clouds of carbon-hydrogen bonds are as far as possible.

(ii) the electron clouds come closer when the staggered form changes to the eclipsed form. It results in increased electron cloud repulsions. Here, molecules will have more energy and lesser stability.

Therefore, the staggered form is more stable.
