What is Fischer indole synthesis explain its mechanism?
The synthesis of Fischer indole is an organic reaction used by an acid catalyst to convert phenyl hydrazine and an aldehyde or ketone to an indole. By the acid catalysed reaction of the hydrazine with the carbonyl, the cycle starts with the formation of a phenylhydrazone.
What is meaning of double salt?
double salt. A salt that crystallizes from an aqueous solution of a mixture of two different ions. The mineral dolomite (CaMg(CO3)2), for example, is a double salt that crystallizes from a solution containing both calcium and magnesium ions. Double salts exist only as solids. Compare complex salt simple salt.
How sodium nitroprusside is formed?
Sodium nitroprusside is a water-soluble salt comprised of ferrous iron complexed with nitric oxide (NO) and five cyanide ions. Acting as a prodrug, SNP reacts with sulfhydryl groups on erythrocytes (as well as albumin and other proteins) to produce nitric oxide (NO).
What is sodium nitroprusside test briefly explain its principle?
Nitroprusside test is a biochemical test used for the detection of the free –SH groups in amino acids or the cysteine amino acid in a protein. The test is a specific test for cysteine as it is the only amino acid with a free –SH group in the structure.
What is the chemical formula of rust?
Rust is hydrated ferric oxide and its chemical formula is Fe2O3. xH2O. The generic name of a very common compound, iron oxide, is rust.
What is ferrocyanide used for?
Ferrocyanide is an odorless yellow solid that mixes with water and is used mainly as an anticaking agent. In this way, it is often added to food grade salt to prevent lumping as well as make sure it’s dispensed smoothly through a salt shaker.
What is sodium carbonate used for?
Uses of Sodium Carbonate (Na2CO3) It is used in the manufacture of detergents, soaps, paper. Also used in the manufacture of water glass (sodium silicate), borax, sodium phosphate, and many other sodium compounds.
How is sodium carbonate manufactured?
Sodium carbonate is manufactured by the thermal decomposition of sodium hydrogen carbonate obtained by Solvay process. The sodium carbonate obtained in this process is dry. It is called soda ash or anhydrous sodium carbonate. Washing soda is obtained by rehydration of anhydrous sodium carbonate.

What are the postulates of Werner’s theory?
The important postulates of Werner’s theory are:
- The central metal or the metal atoms in coordination compounds show two types of valency.
- The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.
- The number of secondary valences is fixed for every metal atom.
How is indole synthesized?
First reported in 1892, the Bischler indole synthesis involves alkylation of an aniline with an α-haloketone, followed by acid-catalyzed ring closure (Scheme 20).
