This is because it can react at more sites and will not be sterically hindered if it is smaller or linear.

WebSo strong bases make good nucleophiles. Sulfur is a larger atom than oxygen, making its electrons more polarizable. Thus, it is a stronger nucleophile than oxygen. However, the pka of R-SH is 8.2 where as the pka of R-OH is 16. Thus, the SH group is a stronger acid than the OH. How can sulfur be both a stronger acid and a stronger base than oxygen?
