1.	Consider the following compounds,The correct decreasing order of stability of compounds is(a) I > III > II > IV(b) IV > II > III > I(c) III > II > IV > I(d) IV > I > III > II
Answer» Answer is : (b) IV > II > III > I +M effect of — NH₂ > +M of —OH group that disperse the charge of carbocation. Hence, increases the stability —CH₃ group shows + I effect, so it will disperse the charge less than —NH₂, —OH group whereas —NO₂ group shows —M/—I effect due to which the positive charge on the carbocation increases. Hence, stability decreases.

Answer»

Answer is : (b) IV > II > III > I

+M effect of — NH₂ > +M of —OH group that disperse the charge of carbocation. Hence, increases the stability —CH₃ group shows + I effect, so it will disperse the charge less than —NH₂, —OH group whereas —NO₂ group shows —M/—I effect due to which the positive charge on the carbocation increases. Hence, stability decreases.
