Whether the acid-catalyzed hydrolysis of acetamide is a reversible or irreversible reaction has to be found and explained. Concept introduction: Acid catalyzed reaction: In acid hydrolysis of amide, acid protonates carbonyl oxygen of amide which increases the electrophilicity of the carbonyl carbon. Water acts as a nucleophile gets attached to the carbonyl carbon of amide to form tetrahedral intermediate(A) which on losing proton get converted to tetrahedral intermediate(B). The nitrogen of tetrahedral intermediate (B) gets protonated to form tetrahedral intermediate(C). The NH 3 group is eliminated from the tetrahedral intermediate (C) and after that, it gets protonated to form NH 4 + . The mechanism of acid-catalyzed hydrolysis of amides is:

3) The following molecule, chloral is a common precursor to chloral hydrate, an acetal type molecule that was a first-generation anesthetic. Draw a mechanism that accounts for tis formation and speculate why it does not require the use of an acid catalyst, like most hemiacetal and acetal reaction: (10 pts) H H₂O

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
