Multiple Choice
Rank the following alkyl halides in increasing order of reactivity in SN1 reaction.
A
I < II < III < IV
B
IV < I < II < III
C
IV < II < I < III
D
IV < I = II < III
0 Comments
Verified step by step guidance1
Identify the type of alkyl halide in each structure. SN1 reactions are favored by tertiary carbons due to the stability of the resulting carbocation.
Examine the structure of compound I. It is a secondary alkyl halide with a bromine atom attached to a carbon that is bonded to two other carbons.
Examine the structure of compound II. It is a secondary alkyl halide with an amino group, which can donate electron density and stabilize the carbocation.
Examine the structure of compound III. It is a tertiary alkyl halide, which is the most stable for SN1 reactions due to the presence of three alkyl groups that can stabilize the carbocation.
Examine the structure of compound IV. It is a primary alkyl halide, which is the least stable for SN1 reactions as the carbocation is not stabilized by additional alkyl groups.
