What is the reflection of the story the mats by francisco arcellana? Hence, anisole reacts with HI to give phenol and methyl . When HI is in excess and the reaction is carried out at a high temperature, the methanol formed in the second step reacts with another HI molecule and gets converted to methyl iodide.

II. What do you understand by the term glycosidic linkage? New questions in Chemistry. When HI is in excess and the reaction is carried out at high temperature, ethanol reacts with another molecule of HI and is converted to ethyl iodide. (i)HI (ii)Bromine water (iii)HNO3. Byjus Asked on June 15, 2016 in Chemistry. Phenyl methyl ether (on anisole) reacts with HI to give phenol and methyl iodide and not iodobenzene and methyl alcohol.

A solution of glucose in water is labelled as 10% w/w, what would be the molality and mole fraction of each component in the solution? Inter state form of sales tax income tax? } H2SO4. Example: anisole undergoes bromination with bromine in ethanoic acid even in the absence of iron (III) bromide catalyst. It is because the attack by I- takes place at that carbon of alkyl group, which has a greater electron pushing inductive effect and a lower electron density. Illustrative of its nucleophilicity, anisole reacts with acetic anhydride to give 4-methoxyacetophenone: CH 3 OC 6 H 5 + (CH 3 CO) 2 O → CH 3 OC 6 H 4 C(O) CH 3 + CH 3 CO 2 H. Unlike most acetophenones, but reflecting the influence of the methoxy group, methoxyacetophenone undergoes a second acetylation. Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why? 39 0 obj <>stream Reason: In case of anisole, methylphenyl oxonium ion, is formed by protonation of ether.
