really the ratio of the rate of the reverse reaction divided by the rate of the forward reaction and so is a dimensionless constant at a given temperature. Additionally‚ functional groups are important for this experiment. Functional group: A group of atoms whose bonding is the same from molecule to molecule. A functional group has

91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1 ‚‚which represents and OH functional group. The second step of the reaction was to oxidize benzoin to form benzil; this reaction yielded 27.04% benzil. The MP of the benzil was 91O-93O C and the IR spectra revealed no OH functional groups. The last step of the synthesis was a double aldol condensation reaction to form tetraphenylcyclopentadienone; this reaction had a yield of 76

bond‚ are important functional groups in natural and synthetic compounds. One method that they can be synthesized is through elimination reactions‚ which form alkenes with the net loss of a leaving group and an H+ on an alpha carbon. Atoms must be attached to adjacent carbons in order to be eliminated. Elimination reactions occur most commonly through E1 and E2 mechanisms. The specific mechanism that occurs depends on various conditions. The various conditions include leaving groups‚ substrate structure

ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including water or alcohol). In the presence of a base‚ the aldol condensation occurs by a nucleophilic addition of the enolate ion (a strong nucleophile) to a carbonyl group. The final step‚ protonation

daily basis. However‚ they are pollutants that cause serious damage to the ozone layer. Nevertheless‚ they are invaluable since they can also be used as intermediates to produce other functional groups (e.g.‚ amines‚ esters‚ and alkenes). Alkyl halides have the general formula RX (where R= alkyl/substituted alkyl group and X = F‚ Cl‚ Br‚ or I.) They are insoluble in water and sulfuric acid and are soluble in organic solvents.[3] They are synthesized for their many uses. There are several ways

Used Fabric Softener as Alternate Air Freshener Submitted to: Sir Elwin Fernandez Background of the Study People nowadays‚ rely on factory made or ready-to-use products. Even if they spend a lot‚ it is alright for them because it is more easy to buy than to make one. Just like air fresheners. Air freshener is one of the important things that you should always have at home. We need this to eliminate bad odours coming from garbage‚ fishy foods

in space. Constitutional isomers are compounds that have the same molecular formula and different connectivity. Isomers have same molecular formula and have different structural formula. Cis isomer has two similar groups on same side of double bond. Trans isomer has similar groups on opposite sides of the double bond. Expanded structural formula is a 2-D structural representation that depicts the bonding of all atoms in a molecule. Condensed structural formula is the structural arrangement

INTRODUCTION Amines are compounds that are composed of a nitrogen atom bearing alkyl or aromatic groups. They are basic and nucleophilic because of their lone pair. They occur both in plants and animals. Amines produces some of the most interesting effects and of the common reaction of aminewith nitrous acid producing a dye[4]. Alizarin‚ for example
