Concept explainers
a)
Interpretation:
The enone product expected from the aldol condensation of cyclopentanone is to be given.
Concept introduction:
To give:
The enone product expected from the aldol condensation of cyclopentanone.
b)
Interpretation:
The enone product expected from the aldol condensation of acetophenone is to be given.
Concept introduction:
Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon of the second molecule. The product obtained, a β-hydroxyaldehyde or ketone upon heating eliminate a molecule of water to yield the enones, α,β-unsaturated aldehydes or ketones.
To give:
The enone product expected from the aldol condensation of acetophenone.
c)
Interpretation:
The enone product expected from the aldol condensation of 2-methylbutanal is to be given.

- 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 H₂Oarrow_forwardYou 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 σarrow_forwardYou are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits.
