Variant ?

 

[ashhadazam]

IF it is variant 2.. then the answer is Pentan-2-ol !! this is because when u r remvong H2) u can remove it from either side of the OH !

 

[ashhadazam]

If it is variant 1.. then J would react with ITESELF to form a cyclic compund... How this happnes :

COnsider that 2 moles of J are present... then the OH from 1st would react with COOH from 2nd and the COOH from the 1st would react with the OH of the second.. Esterification at both ends occur and this monstrous compound is formed

h

 

[WellWIshER]

THEN y do they say it reacts with h2so4???

and its varient 1

 

[ashhadazam]

hahaha.. no its obviously no frm A2.. Its an esterification reaction but a tricky one.. the compund itself has two groups necessary to make an ester.. !!! and H2SO4 catalyses the eserification process. !!!

 

[lastniceboy]
