How do you identify an unknown organic compound?
Structures of unknown compounds can be determined by comparing physical properties, performing functional group tests, and checking melting points of derivatives against those of known compounds reported in the literature. Solubility properties and chemical reactivity become apparent during these qualitative tests.

How do you purify a solid?
Recrystallization is a technique used to purify solid compounds. Solids tend to be more soluble in hot liquids than in cold liquids. During recrystallization, an impure solid compound is dissolved in a hot liquid until the solution is saturated, and then the liquid is allowed to cool.
How do you name a straight chain alkane?
Naming and writing structural and molecular formulas for the straight-chain alkanes is straightforward. The name of each alkane consists of a prefix that specifies the number of carbon atoms and the ending -ane. The molecular formula follows the pattern of CnH2n+2 where n is the number of carbons in the chain.
How do you name an alkane in organic chemistry?
- The locant: The number indicating where the substituent is.
- The prefix: The substituent attached to the alkane. Ends with -yl.
- The Parent: The alkane parent chain. Ends with -ane.
- Suffix: The functional group attached to the alkane. Not always present.

How do you make organic liquids?
- This is used to separate a liquid and soluble solid from a solution (e.g. water from a solution of salt water) or a pure liquid from a mixture of liquids.
- The solution is heated, and pure water evaporates producing a vapour which rises through the neck of the round bottomed flask.

How do you purify organic salt?
1. simply wash the salt with some organic solvents, such as Ethyl Acetate and Hexane and then check the purity using HPLC. 2. Crystallisation such as vapour diffusion of an organic volatile solvent such as ethyl ether into the water solution of your compound will give you a solid which can be separated by filtration.
How do you remove impurities in chemistry?
The impure solid is heated in the minimum amount of hot solvent needed to dissolve the desired compound. The insoluble material is then filtered while the solution is kept hot (called “hot filtration”), and then the desired compound is crystallized and collected by suction filtration.
