Predict the order of reactivity of following compounds in dehydrohalogenation.
`a.` `I. ` `II.`
`III.` `IV.`
`V.`
`b.` `I.` `II.`
`III.` `IV.`

Text Solution

Verified by Experts

`a.` `(V)gt(III)gt(II) gt(IV)gt(I)(` Ease of formation `: 3^(@)gt2^(@)gt1^(@)` carbocation `).`
`1.`
`II.`
`III.`
(Ease of fomation of carbocation is more in `(III)` than in `(II)`, because the reactivity order of `RX` is `RIgt RBrgtRCIgtRF` dur tot he leaving group order of `I^(Θ)gt Br^(Θ)Cl^(Θ)gt F^(Θ)` .)
IV.
`V`
b. `(III)gt(I)gt(II)gt(IV)`
I. II. III. IV. (Neopentyl carbocation is less reactive dur to steric hindrance.)
