Question- Acetylenic fatty acids are found in many tropical plants. Compound H, C18H26O2, is one such compound; it absorbs 5 equivalents of H2 when treated with H2 over a Pd/C catalyst. Ozonolysis of compound H produces the following products: pentanal (CH3(CH2)3CHO) 2-oxoacetic acid (HOOCCHO) oxalic acid (HOOCCOOH) nonanedioic acid (HOOC(CH2)7COOH) Draw the structure of compound H.
