The ability to draw Lewis structures for molecules and ions is a fundamental skill in the study of organic chemistry. The following steps will help you to do this (as you study these steps look at the examples inTable 1.6). As an example, let us draw a Lewis structure of acetic acid, molecular formula C2H4O2. Its structural formula, CH3COOH, gives a hint of the connectivity. 

The vapor density of acetic acid suggests a molecular weight much higher than the formula weight, 60.06. Indeed, the acid normally exists as a dimer (4), both in the vapor phase (5) and in solution (6). This vapor density anomaly has important consequences in engineering computations, particularly in distillations.

The hydrolysis of 3-ethoxy-4-ethylbicyclo[4.1.0]hept-4-en-7-one propylene acetal (1) with aqueous acetic acid in tetrahydrofiiran gives an oil with the molecular formula CnH/gOi, from which the INADEQUATE contour plot 22 and DEPT spectra were obtained. What is the compound ... 

Ocimene is a pleasant-smelling hydrocarbon found in the leaves of certain herbs. It has the molecular formula C10Hi6 and a UV absorption maximum at 232 nm. On hydrogenation with a palladium catalyst, 2,6-dimethyloctane is obtained. Ozonolysis of /3-ocimene, followed by treatment with zinc and acetic acid, produces the following four fragments ... 

The molar mass of acetic acid, as determined with a mass spectrometer, is about 60 g/mol. Using that information along with the simplest formula found in Example 3.6, determine the molecular formula of acetic acid.

Ph, R = H) and acetic anhydride-triethylamine was initially thought to be anhydro-2,3-diphenyl-4-hydroxy-l,3-thiazolium hydroxide, CijHiiNOS (114, R = R = Ph, R = H), but later studies established that the product had the molecular formula C30H24N2O2 and the constitution 116. The synthesis of the meso-ionic l,3-thiazol-4-one (114, R = R = Ph, R = H), orange-yellow needles, m.p. 113°-115°, was successfully achieved by dehydration of the acid (115, R = R = Ph, R = H) using acetic anhydride-triethylamine for a few minutes at room temperature. The acids (115, R = NR2, R = Ph, R = H) and acid anhydrides similarly yield the corresponding meso-ionic l,3-thiazol-4-ones (114, R = NRj, R = Ph, R = H). Analogous polycylic meso-ionic l,3-thiazol-4-ones have also been prepared. ... 

Acetic acid is a weak organic acid whose molecular formula is written as CH3COOH. If an 800 mL aqueous solution of acetic acid is prepared by dissolving 4.8 g of acetic acid ... 

Effect of other factors on cellulose. Dry distillation at a temperature above 150°C causes cellulose to produce compounds of low molecular weight, such as water, methane, ethylene, carbon monoxide, carbon dioxide, acetic acid, and acetone. According to Pictet [49] dry distillation under reduced pressure yields a substance having the empirical formula C6H10Oj, laevo-glucosan which probably is /3-D-glucopyranose anhydride ... 

C104 (not HCIO4). insoluble salts and weak electrolytes are not written in ionic form, even though a minor fraction of each ion may actually exist in solution. For example, we indicate the formula for calcium carbonate as CaC03 (not Ca2+ + CO ). Similarly, for slightly dissociated acetic acid, we use the molecular formula HC2H302 instead flf H+ + C2H302. 

Section 1.7 Table 1.4 in this section sets forth the procedure to be followed in writing Lewis structures for organic molecules. It begins with experimentally determined information the molecular formula and the constitution (order in which the atoms are connected). H 0 = 1 II. .

When C,()HIttFc is reacted with acetic anhydride in the presence of an acid as shown in Reaction ], a dark orange solid is formed with the molecular formula C,2H, OFe. The reaction of C10Hl(,Fe with the anhydride helped scientists to confirm which structure was valid. 

Chlorhexidine is l,6-di(4-chlorophenyl-diguanido)hexane, molecular weight 505.46 g/mole, a cationic bisbiguanide of the formula is shown in Fig. 2.62 and it becomes the diacetate when reacted with two-moles of acetic acid. 

The number of acidic protons is not necessarily the number of hydrogens in the molecular formula. Generally (but not always), acidic hydrogens are listed first in the molecular formula. For example, acetic acid (HC2H302) is a mono-protic acid (Figure 9.3).

Ethanoic acid, more commonly called acetic acid, is responsible for the familiar odor of vinegar, as vinegar is a five percent solution of ethanoic acid. Methanoic acid has the common name formic acid and the formula HCOOH. Notice that in writing molecular formulas, atoms in the functional group are written together, such as in COOH, to show that an acid is indicated.
