Question

In each of the following pairs of ions which ion is more stable:

Answer 1

Correct Answer - (a)I,(b)I,(c)II,(d)II,(e)II
(a). `C_(6)H_(5)-overset(o+)(C)H_(2)`
+M effect of `C_(6)H_(5)` increases the stability
(b). `I^(st)` `CH_(3)-overset(o+)(CH_(2))` electron releasing group.
(c). In `II^(nd)` Resonance stabilises
(d). In `II^(nd)`-1.p. of nitrogen stablises the carbocation.
(e). In `II^(nd)`-negative charge is present on more electronegative element.
