Which of these is most likely to dissolve in 5% NaOH? a) 1-decanol b) decanal c) decanoic acid d) 2-decanone bu itcolf Draw tbeWhen toluene is treated with sulfuric and nitric acids under special conditions, three nitro (NO2) groups are substituted for hydrogens at the 2, 4 and 6 positions on the ring (the next section discusses why the 2, 4, and 6 positions are substituted). The product is a highly explosive substance called 2,4,6-trinitrotoluene. This subastance is commonly known by a three letter name. What is it?Alcohols are important for organic synthesis, especially in situations involving alkenes. The alcohol might be the desired product, or the OH group might be transformed into another functional group via halogenation, oxidation, or perhaps conversion to a sulfonic ester derivative. Formation of an alcohol from an alkene is particularly powerful because conditions can be chosen to produce either the Markovnikov or non-Markovnikov product from an unsymmetrical alkene. Using your reaction roadmap as a guide, show how to convert 4-methyl-1-pentene into 5-methylhexanenitrile. You must use 4-methyl-1-pentene and sodium cyanide as the source of all carbon atoms in the target molecule. Show all reagents needed and all molecules synthesized along the way.
