The two alkanes are n-pentane, C5H12, and n-hexane, C6H14. In addition to carbon and hydrogen atoms, alcohols also contain an –OH group bonded to a C atom in the molecule. Methanol, CH3OH, and ethanol, C2H5OH, are two of the alcohols that we will use in this experiment.

So I was in chemistry class (basics) and teacher wrote up that the intermolecular forces between N2O is suppose to be Hydrogen bonding… Now I don’t really see how. Chemistry Structure and Properties . Intermolecular forces, collectively known as van der Waals’s forces are attractions between discrete molecules.

N2O is a neutral molecule, nitrous oxide, it is isoelectronic with CO2. The intermolecular force which polar molecules take part in are dipole-dipole forces.

Yes: all of them!

Both molecules possess dipole moments but CH3CH2OH contains hydrogen bonded to an electronegative element so H-bonding is possible. Both molecules possess dipole moments but CH3COOH contains hydrogen bonded to an electronegative element so H-bonding is possible.

“Butanol is much better. It contains about 30 percent more energy per gallon than ethanol, is easier to handle and more of it can be blended into each gallon of gasoline. In fact, you could fuel a car on pure butanol and it would run absolutely fine.

Therefore, in the gas-phase, t-butanol is the most acidic alcohol, more acidic than isopropanol, followed by ethanol and methanol. In the gas phase, water is much less acidic than methanol, which is consistent with the difference in polarizibility between a proton and a methyl group.

Amazingly, Propanol is the most time and weight efficient fuel. In fact, none of the fuels changed position in how efficient they were. For both criteria, the fuels were ordered as follows: Best: Propanol Pentanol Butanol Methanol Worst: Ethanol Yet, is this all I can find out about the fuels?

Sanitizer Alcohol Percentage The World Health Organization suggests that 70% ethyl alcohol is superior to isopropyl alcohol against the influenza virus, however, both provide adequate germicidal properties. Ethanol is recommended at higher % concentration, usually 80%.

Ketones contain a carbonyl group (a carbon-oxygen double bond). The simplest ketone is acetone (R = R’ = methyl), with the formula CH3C(O)CH3.

ethanol

Its molecular formula is C2H5OH. Ethanol’s hydroxyl group makes it slightly basic at a pH of 7.33. Ethanol is largely used as an alternative fuel.

1. Nomenclature of Aldehydes and Ketones. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.

aldehyde

Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group….

Ketones are named the same way as are alkenes except that an -one ending is used. The location of the carbonyl group in the molecule is identified by numbering the longest chain of carbons so that the carbonyl group has the lowest number possible.

The functional group of a carboxylic anhydride is two acyl groups bonded to an oxygen atom. The organic anhydrides are used to introduce the acyl group (RCO) in organic synthesis.
