The difference is due to: The Bond Order calculator computes the bond order based on the number of bonding and antibonding electrons. H2O2 has the highest extent of hydrogen bonding because it has two oxygen atoms that are highly electronegative and small in size, making them capable of forming strong hydrogen bonds. The short version: Sulfur is more electronegative than hydrogen, so the H-S bond is polar with electron density higher on the sulfur atom. After the adsorption process, the bonds become significantly longer, which B(aq) + H 2O(l) ⇌ HB + (aq) + OH − (aq) Water is the acid that reacts with the base, HB + is the conjugate acid of the base B, and the hydroxide ion is the conjugate base of water. Symbol (-) indicates gain of electrons. As the size of A increases on descending a group, H-A bond strength decreases and therefore the acid strength Boiling point is inversely proportional to volatility of compounds so its correct order is H 2 O > H 2 T e > H 2 S e > H 2 S.
