O-K+ maybe hinder with the iodoform test

Achcha I see The -OH at C1 will interefere with iodoform test also? 👍

No no, that would have given iodoform test An OH grp connected to a carbon with atleast one hydrogen satisfied the condition The O-K+ is the issue

But it should be methyl hydroxy C right? for +ve iodo?

See, if its a carbonyl, then it must have a CH3 group connected to the carbonyl C and if its OH group, the carbon to which that OH is connected to must have a CH3 group AND it also must have atleast one hydrogen

Ye. So instead pf ch3, we have ch2oh, the reason it won't give iodo, if I understand correctly/

Ohh yeah i was wrong Sorry, see the C1 carbon doesn't have a CH3 grp so even if it didn't have an O-K+ it still won't show iodo
