Why is Cyanoform so reactive?
Cyanoform’s noteworthy chemistry stems from the electron-withdrawing nature of its cyano groups, which creates a very weak link between the central carbon atom and the molecule’s hydrogen atom. The molecule readily gives up its hydrogen, making it a strong acid (pK2 of -5.1 in water).
Which is more acidic chloroform or Fluoroform?
Good question and amazing concept as u might be thinking that fluorine is more electronegative than chlorine than why chloroform is more acidic than fluoroform this because carbonation formed by deprotination of hydrogen in chloroform is stabilised by backbonding as there are empty d orbitals available in chlorine …
Which acid with pKa value is the most acidic?
Sulfuric acid
The key idea to remember is this: the stronger the conjugate acid, the weaker the conjugate base. Sulfuric acid is the strongest acid on our list with a pKa value of –10, so HSO4- is the weakest conjugate base.
What is the pKa of methanesulfonic acid?
-2.0
Ionization Constants of Heteroatom Organic Acids
| Common Name | Formula | pKa |
|---|---|---|
| methanesulfonic acid | CH3SO3H | ca. -2.0 |
| trifluoroacetic acid | CF3CO2H | 0.0 |
| picric acid | (O2N)3C6H2OH | 0.3 |
| squaric acid | 1.5 3.5 |
Which is more acidic CHCl3 or chcn3?
CHI3 3.CH(CN)3 4. CHCl3. is the strongest acid as the conjugate base formed here is stabilized by the mesomeric effect of CN.
Which is more acidic CHCl3 or CHF3?
CHF3 is lesser acidic than CHCl3 .
Why CHF3 is less acidic than CHCl3?
The conjugate base of CHCl3 is more stable than conjugate base of CHF3(CF3). CCl3 stabilized by-I effect of chlorine atoms as well as by the electrons. But conjugate base of CH3(CH3) is stabilized only by-I effect of fluorine atoms.
Why chloroacetic acid is stronger than ch3cooh?
Due to the inductive effect of the chlorine atom the electron density is reduced over the already weakened O-H bond in the carboxylic moiety (due to the presence of alpha carbonyl group) which in turn make it a stronger acid than acetic acid as the ease of releasing the hydrogen to the base is increased.
Is methanesulfonic acid a strong acid?
Methanesulfonic acid (MSA), the simplest alkanesulfonic acid, is a hygroscopic colorless liquid or white solid, depending on whether the ambient temperature is greater or less than 20 ºC. In aqueous solution, it is a strong acid (completely ionized).
Is methanesulfonic acid volatile?
Methanesulfonic acid is used as an acid catalyst in organic reactions because it is a non-volatile, strong acid that is soluble in organic solvents. It is convenient for industrial applications because it is liquid at ambient temperature, while the closely related p-toluenesulfonic acid (PTSA) is solid.
Why is CHCl3 the strongest acid?
Resonating structures are formed between carbon and nitrogen and negative charge lies on nitrogen which gives a stable structure. Hence, the delocalisation of negative charge gives rise to the most stable conjugate base. Therefore, $(D)\,\,CH{(CN)_3}$ is the strongest acid .
How are chloroform and trichloromethane the same?
Chloroform and trichloromethane are two names of one and the same substance, so how is it possible that they have different boiling points? They both are one and the same organic compounds.
What’s the difference between methane and chloroform?
The difference between the boiling point of methane and chloroform. Methan’s boiling point is -164 C and chloroform’s boiling point is 62 C. Explain the difference between two boiling points. I do not get this question at all and really need help answering this particular question.
What’s the boiling point of chloroform at 450 °C?
Chloroform (CHCl3), also called trichloromethane, nonflammable, clear, colourless liquid that is denser than water and has a pleasant etherlike odor with boiling point 61.15 °C (142.07 °F; 334.30 K) decomposes at 450 °C I’m going to assume that you know that chloroform and trichloromethane are the same.
Can a chlorine well cause trihalomethanes to form?
Yes. Dissolved chlorine gas and hypochlorites (liquid sodium hypochlorite or calcium hypochlorite salts) can form THMs. All of these form a free chlorine residual in water, and any free residual can react with organic compounds to form trihalomethanes. Repeated concentrated dosage chlorination of wells to treat biofouling can leave THM residuals.
