Out of Na^(+) andAg^(+) ions, which one is a stronger Lewis acid and why ? |
| Answer» Solution :`Ag^(+)` ion is a stronger Lewis acid than `NA^(+)` ion. Thisis because stronger Lewis acidis ONE which can accepta pair of electrons more easily . `Ag^(+)` ions haspseudo noble GAS configuration ( where outer shell has18 electrons ) wheras `Na^(+)` ion has a noble gas configuartion with 8 electron in the outermost shell. The18 electrons of the outermost shell of `Ag^(+)` ionare DISTRIBUTED as 10 electrons in the inner d-shell and 8 electrons in the outer s and p subshells. The inner d-electrons havepoor screening or shielding effect. As a RESULT, `Ag^(+)` ion hashigher effective nuclearcharge and can take up a pair of electrons more easily. | |
