What is the correct order of decreasing stability of the following cations ? underset(I)(CH_(3)-overset(o+)(C)H-CH_(3)) "" underset(II.)(CH_(3)-overset(o+)(C)H-OCH_(3)) underset(III.)(CH_(3)-overset(o+)(C)H-CH_(2)-OCH_(3))

What is the correct order of decreasing stability of the following cat

1.	What is the correct order of decreasing stability of the following cations ? underset(I)(CH_(3)-overset(o+)(C)H-CH_(3)) "" underset(II.)(CH_(3)-overset(o+)(C)H-OCH_(3)) underset(III.)(CH_(3)-overset(o+)(C)H-CH_(2)-OCH_(3))
Answer» `II GT I gt III` `II gt III gt I` `III gt I gt II` `I gt II gt III` Solution : THUS, the stability of CARBOCATIONS decreases in the ORDER: `II gt I gt III`, i.e., OPTION (a) is correct.
