Ozonolysis data are used to determine the location of the double bonds. The acetone fragment, which comes from carbon atoms 1 and 2 of 2,6-dimethyloctane, fixes the position of one double bond. Formaldehyde results from ozonolysis of a double bond at the other end of B-ocimene. Placement of the other fragments to conform to the carbon skeleton yields the following structural formula for B-ocimene. 

The ozonolysis fragments from myrcene are 2-oxopentanedial (five carbon atoms), acetone (three carbon atoms), and two equivalents of formaldehyde (one carbon atom each). Putting these fragments together in a manner consistent with the data gives the following structural formula for myrcene ... 

Write the structural formula of an aldehyde that is a structural isomer of acetone. 

Such structural formulas could be made more flexible if the existence of two bonds (a double bond) or three (a triple bond) between adjacent atoms were permitted. Thus, ethylene (C2H4), acetylene (C2H2), methyl cyanide (C2H3N), acetone (CsHeO), and acetic acid (C2H4O2) could be represented as follows ... 

Because of favorable dipole-dipole attractions between solvent molecules and solute molecules, polar liquids tend to dissolve in polar solvents. Water is both polar and able to form hydrogen bonds. (Section 11.2) Thus, polar molecules, especially those that can form hydrogen bonds with water molecules, tend to be soluble in water. For example, acetone, a polar molecule with the structural formula shown in the margin, mixes in all proportions with water. Acetone has a strongly polar C = O bond and pairs of nonbonding electrons on the O atom that can form hydrogen bonds with water. 

Give the structural formula for (a) an aldehyde that is an isomer of acetone, (b) an ether that is an isomer of 1-propanol. 

Acetone, used in nail polish remover and as a paint solvent, and propylene oxide, used with seaweed extracts to make food-grade thickeners and foam stabilizers for beer (among other applications) are isomers. Both of these compounds have the molecular formula C3HeO and therefore the same molecular weight. Yet acetone and propylene oxide have distinctly different boiling points and chemical reactivity that, as a result, lend themselves to distinctly different practical applications. Their shared molecular formula simply gives us no basis for understanding the differences between them. We must, therefore, move to a consideration of their structural formulas. 

Give structural formulas for the products formed (if any) from the reaction of acetone with each reagent in Exercise 16.23. 

When a 1 1 mixture of acetone and 2-butanone is treated with base, six aldol products are possible. Draw a structural formula for each. (See Example 15.4)... 

Pentanedione is a considerably stronger acid than is acetone (Chapter 19). Write a structural formula for the conjugate base of each acid and account for the greater stability of the conjugate base from 2,4-pentanedione. 

Draw structural formulas for (1) the alkyltriphenylphosphonium salt formed by treatment of each haloalkane with triphenylphosphine, (2) the phosphonium ylide formed by treatment of each phosphonium salt with butyllithium, and (3) the alkene formed by treatment of each phosphonium ylide with acetone. 

For a clearer understanding, let us consider the number of signals generated by some compounds as examples. Acetone and cyclobutane are cMnsldered first. The structural formulae are given below. 

The ketone functional group is abbreviated —CO—, and the structural formula of acetone is written CH3COCH3. 

Use structural formulas to prepare acetone by oxidation of an alcohol. 

The ball-and-stick model and condensed structural formula are shown for propanone, also known as acetone, which is used as a solvent for paint and nail polish. 

Four different types of solvents were used in this work. The structural formulas of the solvents are given in Fig. 24.1 from left to right for acetone, ethanol, A-methyl-2-pyrrolidon (NMP), and dimethylsulfoxide (DMSO). As those solvents are well-known solvents in process engineering, no detailed description will be given here. Acetone (propanone and AC) and ethanol (ethyl alcohol and EtOH) are both volatile, colorless, flammable liquids, and serve as important solvents. Both solvents are mainly used in this work, as they are also frequently used solvents in the SAS process and comprehensive SAS-specific data is available.
