(a)
Interpretation:
The curved arrow mechanism for the given reaction is to be explained.
Concept Introduction:
The reaction of carbon dioxide with water forms carbonic acid. The carbon dioxide acts as an electrophile. Lone pair of the water molecule acts as the nucleophile. The nucleophilic addition reaction takes place between carbon dioxide and water.
(b)
Interpretation:
The curved arrow mechanism for the given reaction is to be explained.
Concept Introduction:
In the hydrolysis of halo lactone, Grignard reagent is used as an intermediate. The given halo lactone is first converted into alkylmagnesium halide by reaction of halo lactone with magnesium in the presence of ether. Then, the alkylmagnesium halide lactone undergoes hydrolysis in presence of acid.
(c)
Interpretation:
The curved arrow mechanism for the given reaction is to be explained.
Concept Introduction:
The ring opening of the lactone takes place in presence of ethanol and hydrogen bromide to form bromoacid. The bromoacid formed then undergoes esterification reaction to form the bromo ester compound. The esterification reaction is the reaction in which the formation of esters from acid takes place.

- 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
