The molecular formula for the substance formaldehyde is HsCO. Formaldehyde burns to form carbon dioxide and water. What equation represents this reaction ... 

CASRN 637-92-3 molecular formula CeH O FW 102.17 Chemical/Physical The atmospheric oxidation of ethyl ferf-butyl ether by OH radicals in the presence of nitric oxide yielded ferf-butyl formate as the major product. Minor products included formaldehyde and nitrogen dioxide. In the absence of nitric oxide, 2-ethoxy-2-methylpropanal is likely to form (Wallington and Japar, 1991). 

CASRN 75-18-3 molecular formula C2H0S FW 62.14 Photolytic. Sunlight irradiation of a mixture of methyl sulfide (initial concentrations 0.2-2.5 ppm) and oxides of nitrogen (86-580 ppb) in an outdoor chamber at various time intervals (2-7 h) yielded nitrogen dioxide, ozone, sulfur dioxide, nitric acid, formaldehyde, and methyl nitrate, a sulfate aerosol, and methane sulfonic acid (Grosjean, 1984a). 

CASRN 2310-17-0 molecular formula C12H15CINO4PS2 FW 367.80 Plant. Degrades in plants to chlorbenzoxazolone, formaldehyde, and diethyl phosphorodithioate (Hartley and Kidd, 1987). 

The simplest of the aldehydes is formaldehyde, whose molecular formula is HCHO. The second hydrocarbon backbone of the ketone is replaced by a hydrogen atom. Formaldehyde is a gas that is extremely soluble in water it is often sold commercially as a 50 percent solution of the gas in water. The gas itself is flammable, has an ignition temperature of 806°F and a strong, pungent odor, and is toxic by inhalation. Inhalation at low concentrations over long periods of time has produced illness in many people. Beside its use as an embalming fluid, formaldehyde is used in the production of many plastics and in the production of numerous other chemicals. 

Common Name Formaldehyde Synonym formalin, methanal, oxomethane Chemical Name formaldehyde CAS Registry No 50-00-0 Molecular Formula CHjO, FICFIO Molecular Weight 30.026 Melting Point (°C) ... 

Think about the three compounds in Table 3—formaldehyde, acetic acid, and glucose, which is shown in Figure 10. Each has the empirical formula CH2O. However, acetic acid has a molecular formula that is twice the empirical formula. The molecular formula for glucose is six times the empirical formula. The relationship is shown in the following equation. 

In general, the molecular formula is a whole-number multiple of the empirical formula. For formaldehyde, n = 1, for acetic acid, n = 2, and for glucose, n = 6. In some cases, n may be a very large number. 

Ocimene is a pleasant-smelling hydrocarbon found in the leaves of certain herbs. It has the molecular formula CioHig and exhibits a UV absorption maximum at 232 nm. On hydrogenation with a palladium catalyst, 2,6-dimethyloctane is obtained. Ozonolysis of j8-ocimene, followed by treatment with zinc and acetic acid, produces four fragments acetone, formaldehyde, pyruvaldehyde, and malonaldehyde ... 

The empirical formula of formaldehyde is the same as its molecular formula. How many grams are in 2.000 moles of formaldehyde ... 

Melamine is a compound used to make the melamine-formaldehyde resins in very hard surface materials such as Formica . It is 28.57% carbon, 4.80% hydrogen, and 66.63% nitrogen and has a molecular mass of 126.121. What is melamine s molecular formula ... 

Professor Rufus T. Firefly of Fredonia State University wanted to stump his ace chemistry student. Sea Water (C-H2O, alias formaldehyde). The professor asked Sea Water to deduce the structure of menthol, the principal flavoring constituent of peppermint, on the basis of the following data the molecular formula of menthol is C10H20O when heated in the presence of sulfuric acid, a dehydration reaction ensues to form compound A ozonolysis of compound A followed by a reductive workup yields 3,7-dimethyl-6-oxo-octanal menthol also reacts with nitric acid and vanadium oxide, when heated, to form 2-isopropyl-5-methyl-hexanedioic acid. 

Treatment of catechol with formaldehyde in the presence of an acid catalyst produces a compound with molecular formula C7H6O2. Draw the stmcture of this product. 

Now let s consider a molecule in which we have to include multiple bonds when writing the Lewis formula (step 6). Formaldehyde has the molecular formula CH2O, and both hydrogens are attached to carbon. The total number of valence electrons is 12, and 6 of these are accounted for in 3 bonds to carbon. Because oxygen is more electronegative than carbon, we assign the six additional electrons to oxygen. 

A hydrocarbon of molecular formula reacts with Oj followed by workup with (CHjIjS to give formaldehyde and cyclohexane-1,4-dione. Draw the structure of the hydrocarbon. 

Solution (a) Bromine is more soluble in benzene. (b) Sodium iodide is more soluble in water. (c) Carbon tetrachloride is more soluble in benzene. (d) Formaldehyde is more soluble in water. Think About It Remember that molecular formula alone is not sufficient to determine the shape or the polarity of a polyatomic molecule. It must be determined...
