The strain energy determined in prismane should be compared to two three membered and three four membered rings. Concept introduction: Ring strain is a kind of instability that results when bonds deviate from ideal bond-angle. The cyclic system have different amount of strain as illustrated below: It is evident that three and four membered small ring systems have considerable degree of angular and ring strain that leads to their instability. Therefore it can be concluded that as one moves to higher order cycloalkanes, ring size expands and strain diminishes.

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
