b)
Interpretation:
Starting from which alkyne the compound shown can be prepared is to be stated.
Concept introduction:
Carbonyl compounds can be obtained by the tautomerization of enols produced when alkynes are hydrated. The hydration of terminal alkynes can yield an enol which can tautomerize to an aldehyde or ketone. If oxymercuration- demercuration hydration process is used, the OH adds to the more highly substituted carbon in the triple bond following Markovnokov regiochemistry. If hydroboration –oxidation process is used, the OH adds to the less highly substituted carbon in the triple bond following anti-Markovnokov regiochemistry.
To state:
Starting from which alkyne the compound shown can be prepared.

- Calculate equilibrium concentrations for the following reaction:N2 (g) + O2 (g) ⇋ 2 NO (g) Kc = 0.10 at 2273K initially [N2] = 0.200M; [O2] = 0.200arrow_forwardFor each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forwardThe following reaction is run in which the initial conditions include only methane (CH4) at a concentration of0.115 M.
