Identify the reagents to be used in the following synthetic schemes: (Specify the reagents you would use to carry out the conversion by using letters from the table. Write the letters in the order that they are used, e.g., abc Scheme 1 CH Br E CH CH3 Scheme 2 CH CH CH3 CH a. BH3, THF then H202, OH b. PBr3 c. Mg, ether then H3o d. (CH3)2Culi e. Br2 f.

H3O Scheme 1 Scheme 2: abc Submit Answer Try Another Version 3 item attempts remainingExplanation / Answer
Reagents for scheme 1: efg
Explanation: Addition of Br2 to alkene produces a dibromo compound as product. NaNH2 is a strong base which abstracts acidic proton and produces alkyne as product. Addition of H2O to alkyne produces ketone as product.
Reagents for scheme 2: abc
Explanation: Hydroboration - Oxidation of alkene with BH3, THF then H2O2, OH- produces less substituted alcohol as product. reaction of alcohol with PBr3 produces alkyl halide as product. Insertion of Mg metal into alkyl halide produces grignard reagent as product. reaction of grignard reagent with H3O+ produces alkane as product.
