Arrange the following carbocations in increasing order of stability and mention basis of the order suggested
(i) `overset(o+)(C)H_(3)" "`(ii) `CH_(3)overset(o+)(C)H_(2)" "`(iii) `CH_(3)overset(o+)(C)HCH_(3)" "`(iv) `CH_(3)-underset(CH_(3))underset(|)overset(o+)(C)-CH_(3)`

Explanation

To arrange the given carbocations in increasing order of stability, we need to analyze each carbocation based on the inductive effect (I effect) and hyperconjugation. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Carbocations
The carbocations given are:
1. (i) `CH3^+` (Methyl cation)
2. (ii) `CH3-CH2^+` (Ethyl cation)
3. (iii) `CH3-CH^+-CH3` (Isopropyl cation)
4. (iv) `CH3-C(CH3)^+-CH3` (Tert-butyl cation)
