Question
Identify the nucleophile that attacks the carbonado intermediate in this acid-catalyzed hydration. Free radical polymerization of the diene would produce what polymer? Which set of reagents would be best for this conversion? Which products would be formed in this reaction? Which is the major product of this Diels-Alder reaction? What is the reactive intermediate in this reaction? The NaOCH_3 catalyzed reaction between CH_3CH_2CO_2CH_3 An organic compound produces an orange precipitate when treated with 2, 4-dinitrophenylhydrazine in an acidic solution. The compound also reacts with Tolleys reagent. Which compound is consistent with these observations?Explanation / Answer
41) The nucleophile which attacks the C+ intermeidate is H2O ,
42) we get cis diol from alkene and best reganet is OsO4 ( cat) H2O2
43) When Br2 adds we get 1,2 product and 1,4 product ( i.e 1,4 addition) , hence products are I and II
44) Product is reaction B
45) We get polymer as shown in option D
46) CHCl3 on reatcion with base we get :CCl2 which is carbene and it is intermediate
47) NaoCH3 is base and removes alpha Protopn from CH3CH2CO2CH3 and it attacks benzaldehyde C,
we get product D (crossed claisens condestaion )
48) Aldehydes only ( not ketones) give Tollens test psoitive, hence answer is pentanal
