Decreasing order of stability of given carbocations is ?

(2) `CH_(2)=CH-overset(o+)CH_(2)`
(3) `C_(6)H_(5)-overset(o+)CH_(2)`
(4) `CH_(3)-overset(o+)CH-CH_(3)`

Which order is correct regarding stability of intermediates (I). CH_(2)=CH-overset(o+)(C)H_(2) (II). CH_(2)=overset(o+)(C)H (III). CH-=overset(o+)(C)

Arrange the following in increasing order of stability (CH_(3))_(2)overset(o+)(C)-CH_(2)-CH_(3) (2) (CH_(3))_(3)overset(o+)(C) (3) (CH_(3))_(2)overset(o+)(C)H (4) CH_(3)overset(o+)(C)H_(2) (5) overset(o+)(C)H_(2)

The order of stability of the following carbocations: underset("I")(CH_(2)C=CH-overset(o+)CH_(2))" , "underset("II")(CH_(3)-CH_(2)-overset(o+)CH_(2))" , "underset("III")(C_(6)H_(5)-overset(o+)CH_(2))

What si the correct order of decreasing stability of the following carbocations. 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))

Consider the following carbocation- (a). CH_(3)-overset(o+)(C)H_(2) (b). CH_(2)=overset(o+)(C)H (c). CH_(2)=CH-overset(o+)(C)H_(2) (d). C_(6)H_(5)-Coverset(o+)(H)_(2)

CH_(3)-CH_(2)-CH_(2)-O-CH_(3) and CH_(3)-overset(CH_(3))overset(|)(C )H-O-CH_(3) are

CH_(3)-CH_(2)-CH_(2)-O-CH_(3) and CH_(3)-overset(CH_(3))overset(|)(C )H-O-CH_(3) are
