What are the stereochemical configurations of the two diastereomers of (2s,4s)-2,4-hexanediol?
1 answer:
The diastereomerism is the -cis, -trans configuration of molecule.
The R-, S- nomenclature is used to define the aerial position of the functional groups present in a chiral center (the -C molecule at which the four functional groups present around are different) of a molecule. In 2, 4- hexanediol there are two chiral center where the alcohol groups (-OH) are present.
Now the rotation of the stereo centers are analysed by the priority of the functional group. In 2, 4-hexanediol at 2, 4 position the four substituents are -OH, -H, -CH₃ and -C₄H₉O. The priority of the oxygen atom is always to be taken as 1st then -C₄H₉O.
The priority of the group can be shown as -OH > -C₄H₉O > -CH₃ > -H. Thus the rotation will be from -OH to -H which is clockwise. The clockwise rotation is designated as -R configuration but if the -H atom is placed at the horizontal position as present in the figure the configuration will be -S.
Thus the two possible diastereomers of the compound is shown in the figure.

Answer:
The final pressure is approximately 0.78 atm
Explanation:
The original temperature of the gas, T₁ = 263.0 K
The final temperature of the gas, T₂ = 298.0 K
The original volume of the gas, V₁ = 24.0 liters
The final volume of the gas, V₂ = 35.0 liters
The original pressure of the gas, P₁ = 1.00 atm
Let P₂ represent the final pressure, we get;
∴ The final pressure P₂ ≈ 0.78 atm.
