So the idea behind determining which compound is more acidic is linked to the stability of the conjugate bases. The more stable the conjugate base, the easier it is for the compound to lose a proton, the more acidic the compound.
Comparing the two conjugate bases, CF3- and CCl3-. The negative charge on CF3- is stabilised by the induction effect of the electronegative fluorine while the negative charge on CCl3- is stabilised by both induction effects of chlorine and by delocalisation. This delocation can happen in CCl3- because the filled 2p orbitals of C can overlap with the empty 3d orbitals of Cl which lowers the energy. Some people call this backbonding. However F does not have empty d orbitals and this overlap cannot occur.
Therefore, although the induction effect of F is stronger, the combination of induction and back bonding effect better stabilises the conjugate base in CHCl3, making it a stronger acid.
Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product of charge and the bond length.
Chloroform (CHCl3) is the most non-polar among C2H5OH (ethanol), PCl5 (phosphorus pentachloride), and CHCl3. This is because the electronegativity difference between carbon and hydrogen is much smaller than between carbon and chlorine, making CHCl3 more non-polar.
Yes, NO2 is more acidic than CO2.
Resorcinol is more acidic than catechol. This is because resorcinol has three -OH groups that are more acidic than the two -OH groups in catechol.
a lemon is more sour than a grapefruit because it is more acidic.

Anything with a pH of more than 7 is not acidic at all, it is alkaline.
No, beer is actually less acidic than wine.
Resorcinol is more acidic than catechol. This is because resorcinol has three -OH groups that are more acidic than the two -OH groups in catechol.
No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.
No, a pH of 5 is ten times more acidic than a pH o6.
Imides are more acidic than amides because the hydrogen atom in imides is present on a nitrogen atom that is more electronegative than the oxygen atom in amides. This greater electronegativity leads to a more stable conjugate base after deprotonation, making the imide more acidic.
No. Regular Coke is more acidic.
a lemon is more sour than a grapefruit because it is more acidic.
Between blue and purple, blue is more acidic than purple.
