(a)
Interpretation:
The curve arrow mechanism which includes the formation of enamine X is to be stated.
Concept introduction:
The nucleophilic substitution reactions are the reactions in which one nucleophile attacks the electrophilic centre and eliminates another group in the compound. These reactions depend upon the nucleophilicity and concentration of the nucleophile.

(b)
Interpretation:
The curve arrow mechanism for the conversion of enamine X to the given product is to be stated.
Concept introduction:
In Aldol condensation reaction, the base abstracts an acidic proton from the carbon atom to form enolate. This enolate or enol reacts with carbonyl compound that leads to the formation of
The Aldol condensation reaction that takes place within the molecule in presence of strong base is known as intramolecular aldol reactions. This reaction takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate that acts as a nucleophile and reacts with second carbonyl group which acts as electrophile.
(c)
Interpretation:
The hydrolysis mechanism for the reaction that gives the ketone and generates the catalyst is to be stated.
Concept introduction:
The chemical process in which the water molecule is added is known as hydrolysis. The process of hydrolysis prefers acidic condition. The addition of water molecule results in the cleavage of two or more bonds. The water molecule acts as a nucleophile in various reactions such as substitution, elimination and fragmentation reaction.
The products of hydrolysis of imines are carbonyls and amines.

- Select all molecules which are chiral. Brarrow_forwardUse the reaction coordinate diagram to answer the below questions. Type your answers into the answer box for each question. (Watch your spelling) Energy A B C D Reaction coordinate E A) Is the reaction step going from D to F endothermic or exothermic? A F G B) Does point D represent a reactant, product, intermediate or transition state? A/ C) Which step (step 1 or step 2) is the rate determining step? Aarrow_forward1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
