Why are carboxylic acids soluble in basic solutions?
Carboxylic acids contain carboxyl groups (-COOH) that can accept a proton in basic solutions to form carboxylate ions (-COO-), which are generally more soluble due to their negative charge. The increased solubility is also due to the formation of hydrogen bonds between the carboxylate ions and water molecules in the basic solution.
Why acylation occur at phenol rather than carboxylic acid in salicylic acid?
Acylation occurs at the phenol group in salicylic acid due to the higher reactivity of the phenol hydroxyl group compared to the carboxylic acid group. The phenol group is more nucleophilic and readily reacts with acetyl chloride to form acetylsalicylic acid (aspirin). Additionally, the carboxylic acid group can interfere with the reaction due to its ability to form hydrogen bonds, making it less reactive towards acylation.
Ortho effect on acidity of carboxylic acid?
The ortho effect refers to the decrease in acidity of a carboxylic acid when bulky substituents are present at the ortho positions of the phenyl ring. This is due to the steric hindrance caused by the bulky groups, which makes it more difficult for the carboxylate anion to be stabilized, resulting in lower acidity.
When protonation occurs with carboxylic acid why does the H plus cation go to the carbonyl oxygen?
Protonation of a carboxylic acid leads to the formation of the protonated carboxylic acid. The hydrogen ion (H+) tends to bind to the carbonyl oxygen more strongly than to the hydroxyl oxygen due to the higher electron density in the carbonyl oxygen from resonance stabilization in the carboxylate ion. This leads to the formation of a more stable intermediate.
What is the odor produced when carboxylic acid and alcohol is mixed?
This question needs to be more specific - when a carboxylic acid and an alcohol are reacted (usually in the presence of a dehydrating agent, e.g. conc. sulfuric acid), the major product is generally an ester.Esters can have a variety of odours depending on the identity of the carboxylic acid and alcohol. The odour relates to the volatility of the ester, which allows its to be breathed into the nasal passage, and to structural complementarity between the molecule and receptors in the olfactory bulb.I've found a list of common esters and their odours at the bottom of this web page:http://www.3rd1000.com/chem301/chem301v.htmI'm sure that many other sites have more extensive information than this.
Is alkene more water soluble then aldehyde?
Yes
Which acid is more strong stearic acid or citric acid?
stearic acid is more strong i think so..........
Why are carboxylic acids soluble in basic solutions?
Carboxylic acids contain carboxyl groups (-COOH) that can accept a proton in basic solutions to form carboxylate ions (-COO-), which are generally more soluble due to their negative charge. The increased solubility is also due to the formation of hydrogen bonds between the carboxylate ions and water molecules in the basic solution.
Is lauric acid polar or nonpolar?
Lauric acid is a polar molecule due to its carboxylic acid group, which is hydrophilic (water-attracting), making it soluble in water to some extent. However, it also has a long hydrophobic hydrocarbon tail, which can make it more soluble in organic solvents.
What is more reduced lactic or pyruvic acid?
Pyruvic acid is more reduced than lactic acid. This is because yruvic acid contains carboxylic acid and a ketone to oxaloacetate.
What is the name of the ion formed form a carboxylic acid?
The generic term is carboxylate; more specifically, it's the root name of the compound with "-ic acid" replaced by "-ate": acetic acid -> acetate; benzoic acid -> benzoate, etc.
Mandelic acid pka?
The pKa of mandelic acid is around 3.4 for the carboxylic acid group and around 9.8 for the phenolic hydroxyl group. This means that mandelic acid is a weak acid, with the carboxylic acid group being more acidic than the phenolic hydroxyl group.
What is the difference between a carboxylate and a carboxylic acid in terms of their chemical properties and reactivity towards other compounds?
A carboxylate is the ionized form of a carboxylic acid, meaning it has lost a hydrogen ion. Carboxylates are generally more stable and less reactive than carboxylic acids. Carboxylic acids are more acidic and tend to react with other compounds to form salts or esters.
Does ethanoic acid is more soluble than hexanoic acid in water?
Yes, ethanoic acid (acetic acid) is more soluble in water than hexanoic acid. This is because ethanoic acid is a smaller molecule with a polar carbonyl group, allowing it to form hydrogen bonds with water molecules more easily compared to hexanoic acid.
Is sulfuric acid stronger than carboxylic acid?
Acidity is partly determined by its stability of its conjugate base. Once the acid is deprotonated, it is left with a negative charge. Molecules with double bonded oxygens can participate in resonance, which would spread its negative charge over a larger space. Since sulfonic acid has two double bonded oxygens and carboxylic acids only have one, sulfonic acid is more acidic.
Which one is more soluble in water phenol or sodium phenoxide ion?
Sodium phenoxide ion is more soluble in water than phenol. This is because sodium phenoxide ion is an ionic compound, which dissociates into ions in water and forms interactions with water molecules, increasing its solubility compared to the non-ionic phenol molecule.
Which is more acidic methanesulfonic acid or propanoic acid?
Methanesulfonic acid is more acidic than propanoic acid. This is because the sulfonic acid group in methanesulfonic acid is a stronger acid group compared to the carboxylic acid group in propanoic acid.
