- Write the reagent or draw structures of the starting material or organic product(s) in the following reactions. If more than one product is formed, identify the major product where possible. (a) (b) HO OH OH H2SO4 ? Cl₂ ? FeCl3arrow_forwardDraw the skeletal (line-bond) structure of (1R,2S)-1-bromo-2-methylcyclohexanearrow_forward(b) (1-chloromethyl)cyclopentane, CeH11CI reacts with aqueous sodium hydroxide, NaOH to produce a primary alcohol AA. When CeH11Cl is added with magnesium, Mg in ether, an organometallic compound BB is formed. When compound BB reacts with ethanal, CH3CHO, a secondary alcohol cCis formed. The molecular structure of CeH11Cl is given below. (1-klorometil)siklopentana, CoH1,CI bertindak balas dengan akues natrium hidroksida, NaOH bagi menghasilkan satu alkohol primer AA. Apabila CeH11CI ditambah dengan magnesium, Mg dalam eter, sebatian organologam BB terbentuk. Apabila sebatian BB bertindak balas dengan etanal, CH;CHO, satu alkohol sekunder CC dihasilkan.
