(a) Interpretation: The Fisher projection of the given monosaccharide needs to be determined and labeled as D or L sugar. Concept introduction: Fisher projection is a two dimensional representation of a three dimensional molecule. Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

(a)

Interpretation:

The Fisher projection of the given monosaccharide needs to be determined and labeled as D or L sugar.

Concept introduction:

Fisher projection is a two dimensional representation of a three dimensional molecule. Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.

Interpretation Introduction

(b)

Interpretation:

The monosaccharide needs to be classified by determining the type of carbonyl group and number of carbon atoms present in it.

Concept introduction:

Monosaccharide can be characterized according to the type of carbonyl group and the number of carbon atoms in their chain. In the classification of monosaccharide based on type of carbonyl group and number of carbons present in the chain, if the monosaccharide contains an aldehyde group, the prefix aldo- is added to the name and it is called an aldose. On the other hand, if a ketone group is present, it is a ketose or the prefix keto- is added.

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
