The plausible reaction and mechanism should be draw and identified for the given set of aromatic electrophilic substitution reaction under Friedel and crafts' reaction . Concept introduction: Nucleophiles : A nucleophile is a more reactant species that affords a pair of electrons to the electrophile or electrophilic center and forms a new covalent bond. The carbon or other hetero atom in a molecule which is bearing negative charge or lone pair of electron is called as nucleophiles. Electrophile : An electrophile is a species that accepts a pair of electrons to form a new covalent bond. Electrophilic aromatic substitution is anywhere benzene acts as a nucleophile to return a substituent with a new electrophile. The benzene needs to donate electrons from within the ring. Benzene becomes fewer reactive in EAS when deactivating groups are present on it. Deactivating groups are often fine electron-withdrawing groups. Electrophilic substitution reactions are chemical reactions in which an electrophile displaces a useful group in a compound, which is typically, extra than not always, and a hydrogen atom. The other main type of electrophilic substitution reaction is an electrophilic aromatic substitution reaction. Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E 1 (the reaction depends only on the substrate involved in the reaction) or E 2 (the reaction depends on both of the substituents in the reaction) mechanism.

Interpretation Introduction

Interpretation:

The plausible reaction and mechanism should be draw and identified for the given set of aromatic electrophilic substitution reaction under Friedel and crafts' reaction.

Concept introduction:

Nucleophiles: A nucleophile is a more reactant species that affords a pair of electrons to the electrophile or electrophilic center and forms a new covalent bond. The carbon or other hetero atom in a molecule which is bearing negative charge or lone pair of electron is called as nucleophiles.

Electrophile: An electrophile is a species that accepts a pair of electrons to form a new covalent bond.

Electrophilic aromatic substitution is anywhere benzene acts as a nucleophile to return a substituent with a new electrophile. The benzene needs to donate electrons from within the ring. Benzene becomes fewer reactive in EAS when deactivating groups are present on it. Deactivating groups are often fine electron-withdrawing groups.

Electrophilic substitution reactions are chemical reactions in which an electrophile displaces a useful group in a compound, which is typically, extra than not always, and a hydrogen atom. The other main type of electrophilic substitution reaction is an electrophilic aromatic substitution reaction.

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both of the substituents in the reaction) mechanism.

3. 2. 1. On the graph below, plot the volume of rain in milliliters versus its height in centimeters for the 400 mL beaker. Draw a straight line through the points and label it "400 mL beaker." Volume (mL) 400 350 300 250 200 150 750 mL Florence Volume Versus Height of Water 400 mL beaker 100 50 0 0 2 3 4 5 Height (cm) 6 7 8 9 10 Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know? (see page 276 text) the design of the beaker is a uniform cylinder the volume of liquid increases evenly with its height resulting in a linear relationship. What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the graph to assist you in answering the question. 4.

In the video, we looked at the absorbance of a certain substance and how it varies depending on what wavelength of light we are looking at. Below is a similar scan of a different substance. What color BEST describes how this substance will appear? Absorbance (AU) Violet Blue Green Orange 1.2 1.0- 0.8- 0.6- 0.4- 0.2 0.0 450 500 550 600 650 700 Wavelength (nm) violet indigo blue green yellow orange red Red O Cannot tell from this information In the above graph, what causes -450 nm wavelength of light to have a higher absorbance than light with a -550 nm wavelength? Check all that are true. The distance the light travels is different The different data points are for different substances The concentration is different at different times in the experiment Epsilon (molar absortivity) is different at different wavelengths
