- (a) Write the structures of the following compounds and mark them as chiral or achiral. 4 (i) 2-Bromopentane (ii) 3-Bromopentane (iii) 1-Bromo-2-methylbutane (iv) 2-Chloro-3-methylbutane (b) Identify the asymmetric carbon in the chiral compounds. (c) Write the structure of the other enantiomer of the chiral compounds.arrow_forward7.1 Provide the line structures of the products formed in the following reactions. One block may represent more than one product. (a) HBr Diethyl ether (b) H,0, H*arrow_forwardCompound X, C,4H12Br2, is optically inactive. On treatment with strong base, X gives hydrocarbon Y, C14H10: Compound Y absorbs 2 equivalents of hydrogen when reduced over a palladium catalyst to give z (C14H14) and reacts with ozone to give one product, benzoic acid (C,Hg02). Draw the structure of compound Z. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Ignore alkene stereochemistry. • If more than one structure fits the description, draw them all. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate structures with + signs from the drop-down menu. ChemDoodlearrow_forward
