In each reaction box, place the best reagent and conditions from the list below.
Hint: Alkynes are slightly acidic hydrocarbons, a property important in extending the carbon chain. Notice that the product contains two more carbon atoms than the reactant. Note also that the product is a racemic vicinal diol with (R,R) and (S,S) configuration. Which of the reagents can produce a diol?

In each reaction box, place the best reagent and conditions from the list below. A reagent may be used more than once.) Each end of the alkyne chain must be lengthened by two carbon atoms. Propyl bromide in step 2 would add three carbons to one end. 1) 2) CHsCH-CH-Br NaNH2 он NaNH2 3) 4) 5) H3O CH3CH2Br CH3Br CH3CH2CH2Br BH3/THF NaOH NaBH4 H2, Lindlar catalyst H3O H202/NaOH CH3CH2CH2CH2Br NaNH2

In each reaction box, place the best reagent and conditions from the list below. In each reaction box, place the best reagent and conditions from the list below. Only one of the reagents can react with the very unreactive cyclopentane. A radical intermediate is involved. PCC stands for pyridinium chlorochromate. It oxidizes a primary alcohol to an aldehyde or a secondary alcohol to a ketone.

The third step is correct, but the others are not. PCC oxidizes an alcohol to a carbonyl group. Which reagents will convert an alkene to a hydroxyl group, and with the necessary regioselectivity? 2) NaBH in EtOH 3) PCC in CH2Cl2 PhCO3H in CH2012 CH30Na in CH3OH B2H6 in THF in CH2Cl2...
In each reaction box, place the best reagent and conditions from the list below. Hint : The product is an epoxide, so work backwards to determine the intermediate and reagents. A peracid (such as mCPBA) is not available here, so what other method do you know to form epoxides? What reagent and starting material must be used to form this key intermediate? For the epoxide formation, consider the basicity and nucleophilicity of the base. Sapling Learning macmillan learning In each...
