Jones reagent ?

Jones reagent will convert primary and secondary alcohols to aldehydes and ketones, respectively. Depending on the reaction conditions, the aldehydes may then be converted to carboxylic acids. For oxidations to the aldehydes and ketones, two equivalents of chromic acid oxidize three equivalents of the alcohol: 2 HCrO4− + 3 RR'C(OH)H + 8 H+ + 4 H2O → 2 [Cr(H2O)6]3+ + 3 RR'CO For oxidation of primary alcohols to carboxylic acids, 4 equivalents of chromic acid oxidize 3 equivalents of the alcohol. The aldehyde is an intermediate. 4 HCrO4− + 3 RCH2OH + 16 H+ + 11 H2O → 4 [Cr(H2O)6]3+ + 3 RCOOH

ok sir

jones reagent is a powerful reagent

we generally don't use it due to lesser selectivity

ok sir

ok sir

sir here given primary alcohol give aldehyde but in first example it give acid

it's aldehyde

correct it

but sir it also give acid na

no, only aldehyde because it is weak oxidising reagent

let me check

ok sir

The reaction is carried out in an aqueous solution. The aldehyde intermediate is hydrated to form a gem-diol, which is oxidized further to give a carboxylic acid. (Which suggests that anhydrous condition is necessary to stop the oxidation at the aldehyde.)

dekho, agr H2O sath me de rkha he to aldehyde further oxidised to give acid

I can't understand it sir

wait

ok sir

check it

agar only CrO3 diya hua he to only Aldehyde bnega

got it??

agar H2cro4 dia he tho aldehyde and ketones

yes

and if it given with h20 then acid forms

yes

then sir the fast example is correct or not

may be or may not be

because only CrO3 diya he to aldehyde hi bnega

i mean full reaction conditions nhi de rkhi he, only example hi he to bs aap to concept dhyan rkho

ok sir H2cro4 is the jones reagent nasir

or sir only the alcohol primary and secondary having multiple bonds react with this reagent or

the alcohol having single bond also react with this or not

yes, these can react

ye wala case dekho, isme Ya to apko aq. H2SO4 diya hua hoga ya H2SO4/H2O diya hoga to acid bnega

yes H2CrO4 is jones reagent

i think you got it now??

yes sir tho single bond bale alcohol bi jones reagent ke sath react karsaktehena

yes

ok sir know I m clear 😁
