Question

Describe the methods of formation and chemical reactions of thiols.
​

Answer 1

Answer:

because of exothermic reaction

Answer 2

Thiols are usually prepared by using the hydrosulfide anion (-SH) as a neucleophile in an SN2 reaction with alkyl halides. On problem with this reaction is that the thiol product can undergo a second SN2 reaction with an additional alkyl halide to produce a sulfide side product.
