Imagine that the staggered and eclipsed conformers of a small, saturated hydrocarbon are separated in energy by 1.5 kcal/mol. Given this information, what fraction of the molecules would be in the staggered conformation at any given instant? Assume that the sample is at thermal equilibrium at 25 °C, and enter your answer to the nearest hundredth. For example, if the fraction you determined was 1/2, you would enter 0.50 as your answer. Hint: the gas constant, R, equals 1.987 cal/K·mol and T in Kelvin equals the temperature in Celsius + 273; also, assume that all the molecules are either staggered or eclipsed. |

Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

Imagine that the staggered and eclipsed conformers of a small, saturated
hydrocarbon are separated in energy by 1.5 kcal/mol. Given this information,
what fraction of the molecules would be in the staggered conformation at any
given instant? Assume that the sample is at thermal equilibrium at 25 °C, and
enter your answer to the nearest hundredth. For example, if the fraction you
determined was 1/2, you would enter 0.50 as your answer. Hint: the gas
constant, R, equals 1.987 cal/K-mol and T in Kelvin equals the temperature in
Celsius +273; also, assume that all the molecules are either staggered or eclipsed.
