Why Perchloric acid is stronger than sulphuric acid ?

The strength of an acid depends upon the oxidation state of the central atom. More is the oxidation state higher is the acidic character. In case of HClO4(perchloric acid) the oxidation state of chlorine is +7. And in case of H2SO4 (sulphuric acid) the oxidation state of Sulphur is +6 . The oxidation state of

Why sigma bond is stronger than pi bond?

Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formed

Why are ion-dipole attractions stronger than dipole-dipole attractions?

See the ion is a proper charged particle, but dipole is a neutral olecule  which is having polarity in it . the dipole is having temporary charge where as the ion is having a permanent charge. Now lets see the cases Case 1  :-   Ion – dipole attraction Here a permanent ion is attracting a

Why is a Cl-Cl bond stronger than an F-F bond?

This is due to the following two major reasons :- The fluorine atoms are very small in size . The florine element is having the highest electronegativity. Due to these two reasons the florine atoms are so near after the F-F bonding that the start repelling each other due to higher electron desity, which makes

Why methanoic acid is stronger than ethanoic acid?

In case of methanoic acid the carbon atom joined to the carboxyl group is attached to only hydrogen atoms which are not able to increase the electron density. HCOOH  But in case of ethanoic acid we have a methyl group attached to the carbon of carboxyl group , which is electron releasing group and it
