primary alcohol -------> carboxylic acid
reagent : KMnO4 or k2Cr2O7( acidified )
conditions : Reflux

Elimination reaction :
Alcohol --------> alkene
reagent : conc. H2SO4
conditions : heat

add here, 170 C is needed for the elimination reaction

Re: Reagents and conditions for reactions in organic chemist

SN1 mechanisms are observed with tertiary halogenoalkanes or tertiary alcholos, simple substitution takes place. SN2 mechanisms are done by primary ones, transition complexes are formed in it

Hydrolysis of Nitriles ---> produces carboxylic acids
needs dilute HCL

Reduction of NItriles ----> produces Amines
needs LIALH4

alkene ----> alcohols
needs steam, 300C, Ni catalyst
