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 within the same molecule or of the second molecule to give an aldol. The aldol dehydrates on heating to yield α, β-unsaturated aldehyde or ketone.
To show:
The structure of the aldehydes or ketones that should be used as a starting material to synthesize the compound given in an aldol reaction.

Interpretation:
The structure of the aldehydes or ketones that should be used as a starting material to synthesize the compound given in an aldol reaction is to be shown.

Concept introduction:
Mixed aldol condensation leads to a single product if i)one of the carbonyl partners contains no α hydrogen atoms but contains an unhindered carbonyl group and ii) if one of the carbonyl partners are much more acidic than the other and thus forms an enolate anion in preference to other.
To show:
The structure of the aldehydes or ketones that should be used as a starting material to synthesize the compound given in an aldol reaction.

- Please correct answer and don't used hand raitingarrow_forwardneed help please and thanks dont understand a-b Learning Goal: As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7). Part A - Difference in binding free eenergies Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol. The margin of error is 2%.
