The preceding statements by estimating the pK a values of the generic alcohol, amine , alkane , and terminal alkyne species is to be verified. Concept introduction: The strength of two acids can be compared based on the pK a values. The acid with the lower pK a value is a stronger acid than that with a higher pK a value. Each difference of 1 in pK a values represents a factor of 10 difference in acid strength. The strength of an acid increases as the strength of its conjugate base decreases. An electronegative atom accommodate a negative charge better way. A less electronegative atom accommodate a positive charge better way. Stability of a species increases as the number of atoms on which a charge is shared increases. The negative charge on adjescent group or atom is stabilized by an electron-withdrawing groups while it destabilize neighboring positive charges. Electron-donating groups stabilize neighboring positive charges but destabilize adjacent negative charges.

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
