In the following pairs of halogen compounds, which compound undergoes faster SN1 reaction?
The alkyl halide (I) is 2° while (II) is 1°. 2° carbocation is more stable than 1° carbocation. Therefore, (I), 2−chloroheptane, undergoes faster SN1 reaction than (II), 1-chlorohexane.
react faster due to greater stability of 2º carbocation over 1º carbocation.
