A strong acid offers easement in release of proton ( H+).  A weak bond between proton and conjugate base and stable conjugate base offers more Strength to organic acids. Hence, Organic acids strength depend on the  stability of conjugate bases of those acids. Stability of conjugate base depends on following factors: Electronegativity Hybridization Inductive effect Size of conjugate base on which electrons stay In case of acetic acid CH3 COOH, methyl group is electron donating group, hence offer proton to tightly bond with conjugate base acetate ( CH3COO-) and H+ don't get detach from acetate (CH3COO- ) easily . That's why CH3COOH acetic acid is weak acid.  On the other hand in formic acid( HCOOH) , Hydrogen is not enough electron donating atom, make it easy for H+ to get ionize.  That's why, Formic acid HCOOH is stronger acid than acetic acid ( CH3COOH).

All ionic compounds and heteroatomic molecules have charge separation due to electronegativity difference. This charge separation generate dipole moment in molecules.    How charge separation occurs in molecules?    When atoms in molecules have different electronegativity values, more electronegative atoms attracts the bonded pair more towards itself it results in the formation of two opposite charged poles in molecules.In this way charge separation occurs.     There will be strong dipole moment if there is more charge separation in molecules. The charge separation depends on the electronegativity value. Its mean The magnitude of  dipole moment depends on the electronegativity difference. The three parameters - charge separation, electronegativity and dipole moment- are directly interdependent.   DEFINITION : When two opposite unit electrical charges(q) are separated by a distance(r) a dipole created and amount of  dipole is calle...
