WebFeb 12, 2024 · Since, the number of unsaturation within the molecule is zero, we can conclude that the molecule is an alcohol or an ether. The positive blue color test by Victor-Mayer test tell us it is a secondary alcohol. The positive iodoform test tells it has $\ce{CH3CHOH}$ - function. Thus, the structure given for is partially correct. Why partially? WebThe diazomethane is required in excess so as to react with the HCl formed previously. [2] Not taking diazomethane in excess results in HCl reacting with the diazoketone to form chloromethyl ketone and N 2. Mild conditions allow this reaction to take place while not affecting complex or reducible groups in the reactant-acid. [3] simple outdoor bench designs https://jocatling.com
