Question:

Predict the product of the reaction if CH3-S-CH2CH2CH2CH2-Br is heated in a polar organic solvent, such as methanol. Similarly, what would be the product for hexyl bromide in methanol? (In hexyl bromide, note that the S has been replaced by a CH2 group.) Explain why the reaction of CH3-S-CH2CH2CH2CH2-Br is much faster.
