Q.
How many of the total number of compounds that gives positive iodoform test ? CH3CH2OH,PhCHO,CH3COCH3 ((CH)3)2CHOH,HCHO,(CH)3((CH)2)2(COCH)3 PhCH2OH,CH3CH2COPh
Positive iodoform test is given by, i. alcohols containing ((CH)3−CH−OH)∣ group. ii. acetaldehyde (the only aldehyde) and ketones containing ((CH)3CO−) group.
Thus (CH)3(CH)2OH,(CH)3(COCH)3,((CH)3)2CHOH,(CH)3((CH)2)2(COCH)3 will give positive iodoform test.
