What is the least stable conformation of propane?

The least stable (high energy) conformation is the one in which, for any two adjacent carbon atoms, the six bonds (five C–H and one C–C) are as close as possible (eclipsed in a Newman projection).

Which is more stable gauche or anti?

These conformations differ by the relative positions of the two methyl substituents. This is called the gauche conformation. The gauche form is less stable than the anti form due to steric hindrance between the two methyl groups but still is more stable than the eclipsed formations.

Which of the following represents the most stable conformation for propane?

The staggered conformation is the most stable because the bonds are furthest away from each other and the electron repulsions are minimal. The energy difference between the two conformations is called torsional strain.

What is the most stable chair conformation?

The most stable conformation of cyclohexane is the chair form shown to the right. The C-C-C bonds are very close to 109.5o, so it is almost free of angle strain. It is also a fully staggered conformation and so is free of torsional strain.

What is the most stable conformation of cyclohexane?

chair conformation
The chair conformation is the most stable conformer. At 25 °C, 99.99% of all molecules in a cyclohexane solution adopt this conformation.

Which is the most stable chair conformation?

The most stable conformation of methylcyclohexane is the chair conformation in which the methyl group is equatorial. The alternative chair conformation, in which the methyl group is axial, is 7.3 kJ/mol higher in energy.

Which is the most stable conformation of 2 Chloroethanol?

Answer: The most stable conformation of 2-chloroethanol (chlorohydrain) is a) skew.

Which chair conformation is most stable?

cyclohexane
The most stable conformation of cyclohexane is the chair form shown to the right. The C-C-C bonds are very close to 109.5o, so it is almost free of angle strain. It is also a fully staggered conformation and so is free of torsional strain.
