10) What is the product of the following reaction sequence? CH MgBr Ca ECCH3 Ca CH2CH2OH Ca CCH2CH20 CH3 Ca CCII CII CII, II ILL C CCH2O CH2CH3 A) l B) C) lli D) IV E) V 11) The following alkyl halide could not be used to forma Grignard reagent. Explain. HO -CH2CH2-Br 12) Show how the following synthesis could be carried out. CH3 12) Provide the major organic product of the reaction below. CH3CH2MgBr CHINH 13) Provide the major organic product of the reaction below CHI CH2MeBr HAC 140 ls an organolithium reagent more reactive than the comparable Grignard reagent or less reactive? Explain briefly.Explanation / Answer
10) D
11) Mg react with OH group insted of inserting in between alkyl group and Br atom. the compound Mg (O-CH2CH2-Br)2
12) gillmann reagent (CH3)2 CuLi is used first and than treated with acid we get final given product
13) C2H6
14) C2H6
15) YES . RLi is more reactive than RMgX. it is due to in RMgX halogen electon withdrawing group which pull electorons towards itself from alkyl group . but in RLi there is no EWG is present so alkyl group is more negative in RLi compared to RMgX
