for each of the ff predict which will be more acidic and why ? a) HCl vs HBr b)H2O vs H2S c) NH3 vs CH4
Answer : According to the given informations ,
A] The acidity order for the Halogens are The Increasing order of Acidity here will be HF<HCl<HBr<HI Because
Strength of these halogen acids in aqueous solutions increases in the order: HF < HCl < HBr < HI. In this order the H-X bond strength decreases, perceivably due to increase in the size of X (indeed your good reasoning). by the same logic, HBr bond is less stronger than HCl.
B] Here , The H–F bond is more polar than H–O so is easier to break HF into H+ and F- than to break H2O into H+ and OH-. Hence HF is stronger acid thanH2O. S is much larger atom than O, so the H–S bond is much longer and weaker than H–O; hence H2O is weaker acid than H2S.
C] NH3 is the least acidic (most basic) And it has a lewis base due to presense of lone pair it donate line pair and become basic while CH4 is acidic .
Hence it is all about the given question Thank you :)
