Chapter 3: Q14P (page 165)

Draw a perspective representation of the most stable conformation of 3-methylhexane.

Short Answer

Expert verified

The most stable conformation of 3-methylhexane is;

Step by step solution

01

The Conformation.

The conformation is a process of rotating the compound about the sigma bonds to get a different conformational isomer.

02

The skeletal conformer of 3-methylhexane converted to Newman projection.

The given compound consists of 7 carbon atoms, out of which; one carbon atom (methyl group) is attached to the 3rd carbon of the hexane chain.

In the flying wedge projectionof the given compound; the 3rd and 4th carbon are brought in front of each other.

There is one H-atom in 3rd carbon and two H-atoms on 4th carbon.

03

The most stable conformation of 3-methylhexane.

This is the anti-conformation of 3-methylhexane in Newman Projection;

Here, the two bulky ethyl groups are at anti-position and one methyl is in gauche interaction with one of the ethyl groups; making it the most stable conformer.

Question: Conformational studies on ethane-1,2-diol (HOCH2 -CH2OHhave shown the most stable conformation about the central C-Cbond to be the gauche conformation, which is 9.6 KJ/mol (2.3 kcal/mol)more stable than the anti-conformation. Draw Newman projections of these conformers, and explain this curious result.
