Question

Given below are two statements: Statement I: CH\(_3\)-O-CH\(_2\)-Cl will undergo \( S_N1 \) reaction though it is a primary halide.
Statement II: \chemfig{CH_3-C(-CH_3)(-CH_3)-CH_2-Cl}
will not undergo \( S_N2 \) reaction very easily though it is a primary halide. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Statement I is incorrect but Statement II is correct.
• B. Both Statement I and Statement II are incorrect.
• C. Statement I is correct but Statement II is incorrect.
• D. Both Statement I and Statement II are correct.

Hint:

The \( S_N1 \) mechanism involves the formation of a carbocation and is favored by stable carbocations, while the \( S_N2 \) mechanism involves a backside attack and is hindered by steric crowding.

Answer 1

The Correct Option is D

Statement I: CH\(_3\)-O-CH\(_2\)-Cl will undergo \( S_N1 \) mechanism because CH\(_3\)-O-CH\(_2\) is highly stable and can easily form a carbocation.
Statement II: \chemfig{CH_3-C(-CH_3)(-CH_3)-CH_2-Cl}
will not undergo \( S_N2 \) mechanism very easily because it is sterically hindered, making the backside attack difficult. Thus, both statements are correct.
