What are the most acidic hydrogens?
ANSWER: Proton (a) is the most acidic.
Is Cl or CH3 more acidic?
Order of basicity: Cl- (weakest base) < CH3S- < (CH3)2P- (strongest base). Order of acidity: HCl (strongest acid) > CH3SH > (CH3)2PH (weakest acid). The conjugate base of CH3CH2NH2 (ethylamine) has a single resonance contributor, whereas the conjugate base of the amide has two resonance contributors.
Is F or Cl more acidic?
According to organic chemistry as a second language the molecule to the right with fluorine is more acidic than the molecule with chlorine.
How do you know which is most acidic hydrogen?
The hydrogen atom attached to the acidic group will be the most acidic because the hydrogen atom is attached with very electronegative atom oxygen. In a, the hydrogen atom is attached with an oxygen atom which is further attached with a carbon atom having a double bond, so it is an acidic hydrogen.
What is an acidic hydrogen?
Definitions of acidic hydrogen. a hydrogen atom in an acid that forms a positive ion when the acid dissociates.
Which is more acidic HF HCl HBr HI?
Detailed Solution HF < HCl < HBr < HI is the correct increasing order of the acidic strength.
Which is more acidic HI or HF?
HI is a stronger acid than HF.
How do you know which H is more acidic?
Remember that the higher the degree of positive character on the proton, the more acidic it is. Examination of a pKa table reveals some trends for acidic protons.
Is HF or HCl more acidic?
You are correct, HCl is a stronger acid than HF. Fluorine is both more electronegative and smaller than chlorine. Because fluorine is more electronegative, the bond between it and the hydrogen is more polar, meaning that the proton would need to overcome a larger coulomb force to separate from the fluorine.
Which of the following is most acidic?
Presence of electron withdrawing group increases the acidic strength. So, m-chlorophenol is most acidic among all the given compounds.
