- The order of increasing acidity is Phenol < meta-cyanophenol < ortho-cyanophenol 1.how about para-cyanophenol??does it has higher acidicity than both ortho-cyanophenol and meta cyanophenol or lower?? 2.why does ortho-cyanophenol have higher acidicity than meta cyanophenol?? 3. why doesmeta cyanophenol have higher acidicity than PhenolTo preview the image click here Indicate which compound will have highest and lowest Bronsted acidity. 1. Choose the correct option for Highest Bronsted acidity [Select] 2. Choose the correct option for Lowest Bronsted acidity [Select] A B `ОН H3C :0: :0: تصور DWhy is it not advisable to use aqueous hydrochloric acid in a Grignard reaction of a ketone? A) The Grignard reagent will react with the acid and cannot react with the ketone. B) The ketone will be protonated and will become unreactive. C) The ketone will form an unreactive enol. D) The Grignard reagent won't dissolve in aqueous solutions
- Define central relationship between nucleophilicity and basicity in comparing two nucleophiles?Why aldehydes and ketones do not undergo nucleophilic substitution reaction?When trichloroacetaldehyde is dissolved in water, almost all of it is converted to the hydrate. Chloral hydrate, the product of the reaction, is a sedative that can be lethal. A cocktail laced with it is known—in detective novels, at least—as a “Mickey Finn.” Explain why an aqueous solution of trichloroacetaldehyde is almost all hydrate.
- Draw structures for the carbonyl electrophile and enolate nucleophile.Draw the line angle diagram of two different functional groups that act as nucleophiles under acidic conditions. Write the names of the functional groups under each structure.Why is it important that we are very careful in how much acid is added to neutralize the reaction? (Only pick one answer) If the solution becomes very acid it can be harmful to the skin Too much acid will increase vanillyl alcohols water solubility and inhibit crystal formation Too much acid will decrease vanillyl alcohols water solubility and inhibit crystal formation Excess acid will deprotonate the vanillyl alcohol and inhibit crystal formation
