(a)
Interpretation:
The structural formula of missing compound in the given reaction has to be drawn.
Concept Introduction:
Aldehydes and ketones react with alcohol to form hemiacetal as the product. This reacts with further molecule of aldehyde or ketone to form acetal.
Hemiacetal is an addition product that is obtained by reaction between aldehyde or ketone with alcohol. The general reaction of hemiacetal formation can be given as,
Acetal is formed when the formed hemiacetal reacts with further alcohol molecule so that the hydroxyl group in the hemiacetal is converted into alkoxy group. This can be shown as given below,
(b)
Interpretation:
The structural formula of missing compound in the given reaction has to be drawn.
Concept Introduction:
Aldehydes contain a carbonyl group that is bonded to a hydrogen atom and a carbon atom. Ketones are compounds that contain a carbonyl group bonded to two carbon atoms. Aldehydes and ketones undergo addition reaction across the carbonyl group.

- Hello, I am doing a court case analysis in my Analytical Chemistry course. The case is about a dog napping and my role is prosecution of the defendant. I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis. Attached is the following case study reading of my area of expertise! The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data) Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance. Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them.
