q) The correct DECREASING order of priority for the functional groups of organic compounds in the IUPAC system for SO3H,COOH,CONH2,CHO is ?..


 


whenever we name acids , the -oic acid terms comes at the end..so the priority of COOH should be least..????

COOH first.

The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

It is during our darkest moments that we must focus to see the light.

TEMPORARILY RETIRED FROM GOIIT BUT WONT HESITATE TO COME IF I FIND SOME NICE QUESTIONS. :D
