Specific compounds are named in the boxes below and the functional group part of the name is in boldface. For each boldface functional group, draw an expanded structural formula. Indicate the approximate wavenumbers of the IR absorption peaks that could be used to distinguish between the members of each of the pairs of compounds in a row. Mention at least one distinguishing absorption peak for each compound in the pair that is absent in the spectrum of the other compound (except for the compound in the lower right box). Example: acetonitrile and methylamine -C?N -NH2 (primary amine) Nitriles have a CN triple bond stretch at ~2250 cm-1; sharp Primary amines have an NH stretch around 3500-3300 cm-1 that appears as two bands (the CN single bond stretch at 1350-1000 cm-1 is weak and difficult to distinguish). A. 1-propanol B methyl ethyl ether C. 1-pentyne D 1,3-pentadiene E. pentanal F 2-pentanone WIll paypal the first answer correctly given:)
