Which of the following conformations for 1/3 dimethyl cyclohexane is not possible?

The conformer with both methyl groups axial is 3.4 kcal/mole (2 x 1.7 kcal/mol) less stable than the conformer with both methyl groups equatorial. Obviously, the equilibrium will favor the conformer with both methyl groups in the equatorial position.

Which is the most stable conformer for trans-1/3 dimethyl cyclohexane?

Because large groups prefer to be equatorial, the most stable conformer for cis-1,3-dimethylcyclohexane is the diequatorial conformer, shown here. The diaxial conformer would be higher in energy.

What is the order of stability of 1/3-Dimethylcyclohexane?

Answer: The stable conformers of trans-1,3-dimethyl cyclohexane is 1-equatorial-3-equatorial form.

What is the most stable conformation of trans-1/2 Dimethylcyclohexane?

The more stable chair conformation of trans-1,2-dimethylcyclohexane has the two methyl groups in the equatorial position.

Which one of the following conformations of Dimethylcyclohexane is optically active?

Whereas both the a,a and e,e conformation of trans 1,2-dimethylcyclohexane is optically active , can exists in enantiomers and they are resolvable .

What is the structure of 1/3 Dimethylcyclohexane?

1,3-Dimethylcyclohexane

Which of the following is 1 1 Dimethylcyclohexane?

2-Ethyl-1, 1-dimethylcyclohexane.

Does 1/2-Dimethylcyclohexane show geometrical isomerism?

Both molecules can support optical isomerism; but ONLY 1,2-dimethylcyclohexane can support cis-trans isomerism . For (b) , 1,2-dimethylcyclohexane , CLEARLY, the pendant methyl groups can lie on the same side of the ring, or on opposite sides of the ring.

How many stereoisomers does 1/3-Dimethylcyclohexane have?

three stereoisomers
As a result, only three stereoisomers of 1,3-dimethylcyclohexane are observed: cis-1,3-dimethylcyclohexane, which is a meso compound, and a pair of trans-1,3-dimethylcyclohexane enantiomers.

How many isomers does Dimethylcyclohexane have?

There are 7 isomers of dimethylcyclohexane.

Does 1/3 Dimethylcyclohexane show geometrical isomerism?

Therefore, four structural isomers and six geometric isomers are possible for dimethyl cyclohexane.

What is the structure of 1/3-Dimethylcyclohexane?
