Draw all stereoisomers formed when each alkene is treated with CHCl3 and KOC(CH3)3.

CH3 H,C-C=C-C-CH3 H2 ČH3 How to give an alkene compound according to IUPAC

Draw the products formed when the following alkynes are treated with each set of reagents: [1] H2O, H2SO4, HgSO4; or [2] R2BH followed by H2O2, −OH.

Compounds A and B are isomers of the molecular formula CyH19Br. Both yield the same alkene Cin an elimination reaction. Hydrogenation of C yields the product 2,3,3,4 tetramethyl pentane. What are the structures of A, B, and C?

(a) Give the IUPAC name for A and B. (b) Draw the product formed when A or B is treated with each reagent: [1] NaBH4, CH3OH; [2] CH3MgBr, then H2O; [3] Ph3P = CHOCH3; [4] CH3CH2CH2NH2, mild acid; [5] HOCH2CH2CH2OH, H+.

Draw all the alkyl halides with molecular formula C 5H 11Cl formed when pentane (CH 3CH 2CH 2CH 2CH 3) is heated with Cl 2.

Draw the product and indicate the stereochemistry when the given alcohol is treated with each reagent: (a) HBr; (b) PBr3; (c) HCl; (d) SOCl2 and pyridine.
