Identification of unknown organic compound

Solubility Tests The solubility of an organic compound in water, dilute acid, or dilute base can provide useful information about the presence or absence of certain functional groups.

What happened when HNO 3 was added to each precipitate?

Identification of Unknown Organic Compounds A. Zinc chloride a Lewis acid increases the reactivity of alcohols towards acid.

What type of reaction is the reaction between an alkyl halide and alcoholic silver nitrate? Preparation of the reagent: Bromination Test for Alkenes Bromine readily adds across the carbon-carbon double bond of an alkene to produce a dibromoalkane.

Low molecular-weight compounds are generally limited to those with fewer than five carbon atoms.

Heat the mixture to boiling and after the solution has cooled slightly add 2 mL of M hydrochloric acid. Permanganate Test Observations with cyclohexene: Solid bromophenol derivatives can be used for the confirmation of the structure of a phenol cf the preparation of derivatives.

Write up of the identification of an unknown organic compound Date Observations for other compounds: Continue the addition of the reagent until a dark colour is not discharged after 2 minutes heating at A positive test will be a distinct burgundy or magenta colour as compared with the yellow colour observed when the original compound is tested with iron III chloride solution in the presence of acid.

These include aldehydes, some alcohols, phenols, and aromatic amines. Br 2 Br red Br colorless colorless 7.

Identification of Unknown Organic Compounds

Aldehydes also give a positive test. The solution must be kept alkaline if no reaction has occurred, the substance is probably a tertiary amine. Most organic compounds are not soluble in water, except for low molecular-weight amines and oxygen-containing compounds. Any silver fulminate present, which is highly explosive when dry, will be destroyed.1 Identification of Unknown Organic Compounds Introduction The identification and characterization of the structures of unknown substances are an important part of organic chemistry.

Although it is often possible to establish the structure of a compound on the basis of spectra alone (IR, NMR, etc.), the spectra typically must be supplemented with other information about the compound: physical.
