The two reactions above, show routes for conversion of an alkene into an oxirane. If the starting alkene is cis-3-hexene the configurations of the oxirane products, A and B are Product A: _______ Product B: _______ Will either of these two oxirane products rotate the plane of polarization of plane polarized light
Answers
Answer:
Product A and B : (2R,3S)-2,3-diethyloxirane and (2S,3R)-2,3-diethyloxirane.
Explanation:
A double bond is converted to an oxirane through oxidation by peracids e.g. mCPBA (meta-chloroperoxybenzoic acid).
Epoxidation can occur at both face of double bond result in formation of two stereoisomers.
Product A and B : (2R,3S)-2,3-diethyloxirane and (2S,3R)-2,3-diethyloxirane
Both A and B contain plane of symmetry. Hence, both the products are achiral. So, they do not rotate the plane of polarization of plane polarized light.

Explanation
We can use Charle's law to solve this problem.
Charle's law says"at a constantpressure, the volume of a fixed amount of gas is directly proportional to itsabsolute temperature".
V α T
Where V is the volume and T is the temperaturein Kelvin of the gas. We can use this for two situations as,
V₁/T₁ = V₂/T₂
V₁ = 1.00 L
T₁ =?
V₂ = 1.10 L
T₂ = 255 K (Since the unit of the given temperature is missing in the question, thought that the given temperature is in Kelvin)
By applying theformula,
1.00 L / T₁ = 1.10 L / 255 K
T₁ =(1.00 L / 1.10 L) x 255 K
T₁ = 231.8 K
Hence, the initial temperature is 231.8 K.
Assumption : the pressure of the gas is a constant.
Hello!
What is the initial temperature of a gas if the volume changed from 1.00l to 1.10l and the final temperature was determined to be 255 ?
We have the following data:
V1 (initial volume) = 1.00 L
V2 (final volume) = 1.10 L
T1 (initial temperature) = ? (in Kelvin)
T2 (final temperature) = 255 K
According to the Law of Charles and Gay-Lussac in the study of gases, in an isobaric transformation, ie when a mass under pressure maintains its constant pressure, on the other hand, as the volume increases, the temperature increases and, if the volume decreases, the temperature decreases (directly proportional to temperature and volume) . We apply the data to the formula of isobaric transformation (Charles and Gay-Lussac), we will see:
multiply the means by the extremes
Answer:
The initial temperature is approximately 231.8 Kelvin

Mendeleeve's periodic table was based on the atomic mass of each element.
The correct answer is option A: He determined the mass of atoms of each element.
The periodic table can be described as a regular arrangement of elements based on some periodic properties. The periodic table has evolved through the ages. Its patter has been changed several times before it arrived at its present form.
The Mendeleev periodic table was based on the mass of atoms of the elements. This table was published in Russia in 1869. His table even predicted elements that were yet to be discovered.
