What are the key reactions of NaOH in organic chemistry?
In organic chemistry, NaOH (sodium hydroxide) can undergo key reactions such as nucleophilic substitution, elimination, and saponification. Nucleophilic substitution involves the replacement of a leaving group by the hydroxide ion from NaOH. Elimination reactions involve the removal of a proton and a leaving group to form a double bond. Saponification is a reaction where NaOH reacts with esters to form soap and alcohol.
What happens when an ester is reacted with NaOH?
When an ester is reacted with NaOH, it undergoes hydrolysis to form the corresponding carboxylate salt and alcohol. The reaction is typically called saponification and is often used in the production of soap.
What is the products of the saponification of tripalmitin?
Tripalmitin is a 16 carbon saturated fatty acid. Saponification is a reaction involving a strong base (ex: NaOH) and a fatty acid. The reaction yields a glycerol and 3 fatty acid salts. Therefore the reaction products are: glycerol: CH2(OH)--CH(OH)--CH2(OH) + 3 fatty acid salts: CH3--(CH2)14--COO(-) Na(+) + 3H2O Above is actually a summary of what is in reality a 2-step reaction: the fatty acid reacts with H2O first to yield a glycerol and 3 fatty acids; the fatty acids subsequently reacts with the alkaline (base) (NaOH) to yield 3 fatty acid salts and H2O
Base hydrolysis of an ester is called?
Base hydrolysis of an ester is known as saponification, where the ester is hydrolyzed in the presence of a strong base (e.g. NaOH) to form a carboxylate salt and an alcohol. This reaction is commonly used in soap-making processes.
Is oleic acid soluble dilute NaOH?
Yes, oleic acid is soluble in dilute NaOH due to the formation of soap through saponification reaction. Oleic acid reacts with NaOH to form the sodium salt of oleic acid, which is a soap that is water-soluble.
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH
Why initial products of the saponification of methyl benzoate soluble in water?
The initial products of saponification of methyl benzoate are the sodium salt of benzoic acid and methanol. The sodium salt of benzoic acid is soluble in water because it forms ionic bonds with water molecules. Methanol is also soluble in water due to its polar nature, allowing it to hydrogen bond with water molecules.

How many products would saponification yield?
2
What are two products of saponification?
Ethyl Alcohol + Ethanoic Acid
What is the catalyst needed for saponification?
The catalyst needed for saponification is typically an alkali, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). These alkalis help to hydrolyze ester bonds in fats or oils, leading to the formation of soap.

What happens when a fatty acid is reacted with NaOH?
When a fatty acid is reacted with NaOH, a process called saponification occurs. This reaction results in the formation of soap, which is a salt of the fatty acid alongside glycerol. This reaction is commonly used in soap-making processes.
What is the formula to calculate saponification number?
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
