Isopropyl alcohol structural formula

Organic chemists have devised a number of shortcuts to speed the writing of structural formulas Sometimes we leave out unshared electron pairs but only when we are sure enough m our ability to count electrons to know when they are present and when they re not We ve already mentioned representing covalent bonds by dashes In condensed structural formulas we leave out some many or all of the covalent bonds and use sub scripts to indicate the number of identical groups attached to a particular atom These successive levels of simplification are illustrated as shown for isopropyl alcohol ( rub bmg alcohol )... 

The substitution of one hydroxyl radical for a hydrogen atom in propane produces propyl alcohol, or propanol, which has several uses. Its molecular formula is C3H7OH. Propyl alcohol has a flash point of 77°F and, like all the alcohols, bums with a pale blue flame. More commonly known is the isomer of propyl alcohol, isopropyl alcohol. Since it is an isomer, it has the same molecular formula as propyl alcohol but a different structural formula. Isopropyl alcohol has a flash point of 53 F. Its ignition temperamre is 850°F, while propyl alcohol s ignition temperature is 700 F, another effect of the different stmcture. Isopropyl alcohol, or 2-propanol (its proper name) is used in the manufacture of many different chemicals, but is best known as rubbing alcohol. 

Consider isopropyl alcohol, C3H80. It is the component of rubbing alcohol and is also present in many household glass cleaners. Its structural formula is... 

Self-Test C.1A Draw the structural formulas of (a) 2,2-dimethylbutane, (CF CCF CHj, which is obtained from petroleum, and (b) 2-propanol (10), which is commonly sold as isopropyl alcohol. 

The structural formula of isopropyl alcohol, better known as "rubbing alcohol," is shown. What is the chemical formula of isopropyl alcohol ... 

The resin was placed in a vacuum of 30 in Hg for two hours, then sealed in a nitrogen atmosphere. Resin with a higher hydroxyl content was prepared in a similar manner except before sealing the bottle, isopropyl alcohol (Reagent, Lehigh Valley Chemical) was added. Characterization of these materials by a modified procedure of Knoll et al (14) gave the epoxide content. Table I. Hydroxyl content was calculated from the structural formula. 

Isopropyl alcohol resembles other alcohols in showing the chemical properties characteristic of compounds which contain an alcoholic hydroxyl group. Its oxidation to acetone shows that it is a secondary alcohol, and leads to the conclusion that its structure is represented by the formula (CH3)2CHOH. Isopropyl alcohol boils at 82.1° and has the specific gravity 0.7887... 

The only 2 carbon alcohol portion possible is ethyl, which means the acid portion must be n-propyl. (The isopropyl configuration is not possible since the acid synthesized from the alcohol (ethyl) by carbonation of a Grignard reagent will be a straight chain also.) Therefore, the structural formula of A becomes ... 

In earlier chapters, and above, I have shown how Kekule used his sausage formulas and models with heuristic confidence, even while disclaiming a realistic interpretation of them. He was convinced that valence was a constant rather than a variable quantity for any element he rejected out of hand the notion that two affinities of a single atom could satisfy one another he provided an appealing model for theories of double bonds, triple bonds, and unsaturated affinities ("gaps"), as well as a way easily to distinguish "atoms of the radical" versus "atoms of the type" he was led to conclusions regarding certain structures (e.g., of pyrotartaric acid and of isopropyl alcohol) that other structuralists immediately jumped on as errors and he discussed different theoretical options for the benzene nucleus. All of these are examples of positions that can be deduced or otherwise derived from contemplation of... 

Ethene, written as H2C=CH2 or CH2=CH2, and propene, CH3CH=CH2, are the first two members of the alkene family. These two alkenes are often called by their common names, ethylene and propylene, respectively. They are two of the most important chemicals produced by the chemical industry in the United States. Ethylene is used in the production of polyethylene, one of the most useful plastics produced, and in the production of ethylene glycol, the principal ingredient in most antifreeze. Propylene is used in the production of isopropyl alcohol (rubbing alcohol) and some plastics. Figure 14-7 shows a couple of ways to represent the structural formula of ethene (ethylene). 

Ethylmethyl ether. ChHsO, has the same molar mass as isopropyl alcohol but a different structural formula (CH3—O—C2H5). Compare their normal boiling points and solubilities in water.
