Which is a stronger acid between CH2FCOOH and ch2brcooh?

Thus in summary, acidity goes up in HF -> HCl -> HBr -> HI because of less relative overlap due to size of the halide orbital, and acidity goes down in CH2FCOOH -> CH2ClCOOH -> ……. due to increases electronegativity and stronger binding of the COOH.

Why is CH2FCOOH a strong acid?

With the other two, fluorine is more electronegative than chlorine, and so is more effective at reducing the charge around the COO- end. So CH2ClCOOH is next in the list, and CH2FCOOH is the strongest of these acids.

Which acid is stronger CH2FCOOH or CH2ClCOOH?

CH2FCOOH is more acetic because of a higher electron negive atom F in in it than Cl. Thus it will allow easier formation of an H+ ion and is more acidic in nature.

Why ClCH2COOH is stronger acid than BrCH2COOH?

Give reason. The stronger the electron withdrawing group the greater is the strength of the substituted carboxylic acid. Since fluorine is most electronegative and strongest electron withdrawing group, therefore, fluoroacetic acid F CH2COOH is stronger as compared to chloro, bromo and iodo acetic acids.

Which one is strongest acid among following options a ch2fcooh?

Answer: C COOH is the strongest acid among the following options.

Which is more acidic FCH2COOH or CH3COOH?

Electron withdrawing substituent increases the acidity by increasing the ionic character of O–H by inductive effect. Electronegativity decreases in the order F > Cl > Br and hence –I effect also decreases in the same order therefore the correct option is FCH2COOH > ClCH2COOH >BrCH2COOH > CH3COOH.

Which is the strongest acid in the following Ch2FCOoH?

Which acid of each pair shown is more stronger and why?

Hence, CH2FCO2H is stronger acid than CH2ClCO2H. Inductive effect decreases with increase in distance. Hence, the +I effect of F in CH3CHFCH2CO2H is more than it is in CH2FCH2CH2CO2H.

Which is the stronger acid in the following pair?

Ernest Z. H2SeO4 is the stronger acid.

Why ClCH2COOH is more acidic than CH3COOH?

Solution 1. Cl-CH2COOH is a stronger acid than CH3COOH : Chlorine is a electron withdrawing group and its increase the acidity of carboxylic acids by stabilising the conjugate base due to delocalisation of the negative charge by resonance effects.
