Why is Lewis concept more useful than Bronsted-Lowry concept? |
|
Answer» ng to Bronsted-Lowry concept, acid is a substance which donates hydrogen ion and base is a substance which accepts hydrogen ion. Here HA is the Bronsted acid and Z is the Bronsted base. Moreover only when we observe the reaction equation we can tell which species is Bronsted acid and which one is the Bronsted base. (Here accepts a proton; hence Bronsted base) (Here the same donates a proton; hence Bronsted acid)According to LEWIS concept acid, it is a substance which accepts a pair of electrons (electrophilic- electron attracting) and base is a substance which donates those pair of electrons in other words a NUCLEOPHILE. \Lewis BASES have LONE pair of electrons. Hence we can very easily identify the Lewis acids and bases. |
