Arrange stability of the given carbon cation in decreasing order

Step-by-step solution

The stability of carbocations is determined by the electron-donating or electron-withdrawing nature of the substituents attached to the benzene ring. The carbocations are stabilized by resonance from the lone pairs on the substituents at the para position. The substituents are: (i) -OCH₃ , (ii) -OH , (iii) -NH₂ , and (iv) -Cl . The resonance donating ability of these groups depends on the electronegativity of the atom directly attached to the ring. A less electronegative atom donates its lone pair more effectively
