here is some properties of reagents in organic chemistry .......hope its useful.....



 

Name of Reagent Conditions Example of its Use
K2Cr2O7 with conc. H2SO4 Warm gently Oxidising agent, used commonly for oxidising secondary alcohols to ketones.
Excess conc. H2SO4 heat to 170 C Dehydrating agent, used to dehydrate alcohols to alkenes.
Cl2(g) Ultra Violet light Free radical reaction, used to convert alkanes to haloalkanes.
Br2 in CCl4 Room temperature, in the dark Electrophilic addition, converts alkenes to dihaloalkanes.
H2(g) Nickel catalyst, 300 C and 30 atmospheres pressure Hydrogenating agent, used to convert benzene to cylcohexane.
H2(g) Nickel catalyst, 150 C Reducing agent, used to convert alkenes to alkanes
Tin in hydrochloric acid Reflux Reducing agent for converting nitrobenzene to phenylamine.
Acidified KMNO4 Room temperature Oxidising agent, converts alkenes to diols.
NaOH in ethanol Reflux Elimination reaction, converts haloalkanes to alkenes.
Aqueous NaOH Reflux Nucleophilic substitution, converts haloalkanes to alcohols.
Mg in dry ether Reflux Used to make grignard reagents with haloalkanes.
PCl5 Room temperature Chlorinating agent, reacts with OH group in alcohols and carboxyllic acids
HNO3 and H2SO4 55 C Adds NO2 group onto benzene ring.
Cl2 and AlCl3 Warm gently Adds Cl group onto benzene ring.
CH3CH2Cl and AlCl3 Warm gently Adds CH3CH2 group onto benzene ring.
HCl and NaNO2 Below 5 C Forms diazonium salts with phenylamine.

these little amount reagents we can get easily the other major reagents where we'll get them like the reagents used in coreyhouse rxn, wittig rxn etc.
