What would be the order of increasing acidic strength in the following : HCF3, HCCl3, HCBr3?

Question

Answer

Target neet 2018 u went wrong,,,crct ans is HCCl3>HCF3>HCBr3,,,n guys u think that F is more electronegative than Cl so that CF3(-) conjugate base sd more stable bt actual thing is there is a repulsive force between the l.p. electrons,,bt in CCl3(-) Cl atom has d block so the lone get fused in d block n the bond type is 2pπ-3dπ..so  conjugate base CCl3(-) more stable than CF3(-) hence HCCl3(-) is more acidic than HCF3(-)

Answer

Answer

HCCL3 > HCF3 > HCBr3

Answer

CHCl3 > CHF3> CHBr3..reason--as usual acc to -- I effect, order is F>Cl>Br.. but in CHCl3 there is back bonding in CCl3 minus, which makes it more stable.. so CHCl3 is more acidic. rest is acc to  - I effect..

Answer

I think  CH3Br >CH3Cl> CH3F  because pka  value is less in 1st  case  also it's dipole  interaction  is higher

Answer

Order of Increasing Acidic Strength

HCF3

HCBr3

HCCl3

Explanation

The acidity of a molecule is determined by its ability to donate a proton or hydrogen ion (H+). The stronger the molecule's ability to donate H+, the stronger the acidity. In the case of the given molecules, the order of acidity strength can be explained based on the following factors:

Electronegativity

The electronegativity of the halogen atoms in the molecules increases in the order F < cl='' />< br.='' this='' means='' that='' the='' halogen='' atom='' in='' hcf3='' is='' the='' least='' electronegative='' and='' the='' halogen='' atom='' in='' hcbr3='' is='' the='' most='' />

Stability of Conjugate Base

The stability of the conjugate base formed after the molecule donates H+ also affects the acidity strength. The more stable the conjugate base, the stronger the acidity.

In the case of HCF3, the conjugate base CF3^- is highly stable due to the presence of three fluorine atoms that can disperse the negative charge. This makes it difficult for HCF3 to donate H+ and hence it is the least acidic.

On the other hand, the conjugate base formed after the donation of H+ by HCBr3 is less stable due to the presence of the highly electronegative Br atom. This makes it easier for HCBr3 to donate H+ and hence it is the most acidic.

In conclusion, the order of increasing acidic strength in the given molecules is HCF3 < hcbr3='' />< hccl3.='' />

Answer

HCF3>HCCl3>HCBr3

Answer

Yes ..u r wrong dear...it's just reverse...

Answer

I think target neet 2018 is correct

Answer

HCCl3>HCF3>HCBr3 due to d orbital resonance

Answer

Monesh is correct .. cause Cl is more electronegative than F ..And question is on HCF3,HCCl3 and HCBr3 .. but @target Neet2018 give answer for  CH3F,CH3Br and CH3F

Answer

CHF3>CHCl3>CHBr3

Answer

CHBr3>CHCL3>CHF3 ...Just Make A Conjugate base, After That..Fluorine has Strongest -I effect among other Halogens...So 3 Flourines are  Destabilizing Conjugate acid Most
