WebIodoform (HCI3) is an analogue of chloroform (HCCl 3) but with rather different properties. It is a pale yellow, somewhat oily solid at ordinary temperatures. It has long been used as an external disinfectant and wound dressing in general medical contexts,[24] although it is now uncommon for a variety of reasons. WebIodoform (JP15/USP) Molecular Formula CHI. 3. Average mass 393.732 Da. Monoisotopic mass 393.721191 Da. ChemSpider ID 6134.
Iodoform - Explanation, Characteristics, Uses Turito
WebWhen ethanol is warmed (60°C) with iodine in the presence of an alkali (NaOH, or Na 2 CO 3 ), iodoform is obtained. Step 1: NaOH + I 2 NaI + H 2 O. Step 2: Oxidation of ethanol to ethanal (acetaldehyde). Step 3: Ethanol so formed undergoes iodination. Step 4: Hydrolysis (cleavage) of Cl 3 CHO by alkali. Cl 3 CHO + NaOH + HCOONa. Web(a) (i) Propanone gives iodoform test while propanol does not give this test. (ii) Benzaldehyde (C 6 H 5 CHO) and acetophenone (C 6 H 5 COCH 3) can be distinguished by iodoform test.. Acetophenone, being a methyl ketone on treatment with I 2 /NaOH undergoes iodoform reaction to give a yellow ppt. of iodoform. On the other hand, … ipn ou hea
