Stearic hindrance
網頁2024年3月15日 · Steric hindrance (SH) is often considered to be one of the dominant factors determining the most favorable reaction out of the SN2 and E2 pathways. … 網頁The steric hindrance caused by the substituents in the ortho position, other than aliphatic groups, decreases the basicity; thus, a value of –n.0.29 (where n = 2 or 3 if there are one or two ortho-position substituents in question) must be added. –
