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

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
