Question

List the following compounds in order elimination. mg compounds in order of increasing reactivity in an e CH3CH2CHBrCH, CH3CH2CH2CH2Br, (CH3)3CDF

Answer 1

2.

A:- E1 elimination reaction order of reactivity is increases with increasing stability carbocation, that means the stability carbocation increases from primary carbocation to secondary carbocation to tertiary carbocation.

CH3^+    <       CH3CH2^+ <        (CH3)2CH^+             <                   (CH3)3C^+

              primary carbocation                                   secondary carbocation    tertiary carbocation

As similar as the reactivity order of E1 reaction increases as follows,

CH3CH2CH2CH2Br    <        CH3CH2CHBrCH3    < (CH3)3CBr

primary alkyl halide                   secondary alkyl halide              tertiary alkyl halide
