(a)
Interpretation:
A mechanism of given reaction under neutral condition is to be drawn.
Concept introduction:
The carbonyl carbon is electrophilic in nature due to the electronegativity difference between the carbonyl carbon and oxygen. Since water is amphoteric in nature can act as acid as well as a base depending on availability and the reaction condition. Under neutral conditions, water acts as the nucleophile.

Answer to Problem 18.1P
A mechanism of given reaction under neutral condition is:
Explanation of Solution
The given reaction is:
Under neutral conditions, water acts as the nucleophile. The electrophilic addition step increases the total number of charges by two as shown below,
Under neutral conditions, water acts as a nucleophile.
(b)
Interpretation:
A mechanism of given reaction under basic condition is to be drawn.
Concept introduction:
Under basic conditions, the nucleophile becomes stronger and the electrostatic attraction is increased when the uncharged nucleophile is converted into a negatively charged nucleophile.

- Provide the IUPAC name of the following molecule. Don't forget to include the proper stereochemistry where appropriate.arrow_forward3. 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. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a best-fit curve through the points and label it "250 mL Florence flask." oke camearrow_forwardShow work. Don't give Ai generated solutionarrow_forward
- 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.
