In the following carbocation, H//CH_(3) that is most likely to migrate to the positively charged carbon is {:(""H""H),("|""|"),(H_(3)overset(1)(C)-.^(2)C-._(3)overset(+)C-C^(4)-overset(5)(C)H_(3)),("|""|""|"),(""HO""H""CH_(3)):}

Answer»

`CH_(3)` at C-4
H at C-4
`CH_(3)` at C-2
H at C-2

Solution :In the given carbocation, `H^(-)` migrates from C-2 to C-3 because
(i) the +ve CHARGE GENERATED on C-2 in I is in CONJUGATION with the n-electrons of the O atom

(ii) It is STABILIZED by +I EFFECT of `CH_(3)` group.
