2, 4-DNP
Tollen's reagent
One mole of an organic compound A with the formula C3H8O reacts completely With two moles of HI to form X and Y. When Y is boiled with aqueous alkali it forms Z. Z answers the iodoform test. The compound A is
propan-2-ol
propan-1-ol
ethoxyethane
methoxyethane
D.
methoxyethane
Molecular formula C3H8O (CnH2n+2O) suggests that the organic compound is either alcohol or ether.
Since, the compound on reaction with HI gives two different compounds, it must be an unsymmetrical ether, and its formula must be CH3OC2H5 (methoxyethane).
The reaction are as follows
The correct sequence ofsteps involved in the mechanism of Cannizaro's reaction is
nucleophilic attack, transfer of H- and transfer of H+
transfer of H-, transfer of H+ and nucleophilic attack
transfer if H+, nucleophilic attack and transfer of H-
electrophilic attack by OH-, transfer of H+ and transfer of H-
