Configuration of the given alkene has to be identified from the given options. Concept Introduction: Alkenes are hydrocarbons that contain at least one double bond in it. There will not be any free rotation of the double bond in alkene. Hence, cis‑trans isomerism is possible. The first and foremost condition for the alkene to exhibit cis‑trans isomerism is that the carbon attached in either end of double bond must have different groups attached to it. A cis isomer is the one in which the same groups are present on same side of both the carbon atoms present in the double bond. A trans isomer is the one in which the same groups are present on opposite side of both the carbon atoms present in the double bond. Cis‑trans isomerism is not possible if any one of the carbon atom bonded to the double bond bears two identical groups. Cis‑trans isomers are not constitutional isomers but they are stereoisomers.

Interpretation Introduction

Interpretation:

Configuration of the given alkene has to be identified from the given options.

Concept Introduction:

Alkenes are hydrocarbons that contain at least one double bond in it. There will not be any free rotation of the double bond in alkene. Hence, cis‑trans isomerism is possible. The first and foremost condition for the alkene to exhibit cis‑trans isomerism is that the carbon attached in either end of double bond must have different groups attached to it.

A cis isomer is the one in which the same groups are present on same side of both the carbon atoms present in the double bond.

A trans isomer is the one in which the same groups are present on opposite side of both the carbon atoms present in the double bond.

Cis‑trans isomerism is not possible if any one of the carbon atom bonded to the double bond bears two identical groups.

Cis‑trans isomers are not constitutional isomers but they are stereoisomers.

3) Determine if the pairs are constitutional isomers, enantiomers, diastereomers, or mesocompounds. (4 points)

In the decomposition reaction in solution B → C, only species C absorbs UV radiation, but neither B nor the solvent absorbs. If we call At the absorbance measured at any time, A0 the absorbance at the beginning of the reaction, and A∞ the absorbance at the end of the reaction, which of the expressions is valid? We assume that Beer's law is fulfilled.
