Abstract
I SUBMIT that the interpretation given above by Profs. Ingold and Hughes for the passage which I quoted1 is not made clear in the original text2. What I see expressed in the paper regarding the bimolecular reactions of R-Hal for the Me, Et, n-Pr, i-Bu, neopentyl series can be illustrated once more by Prof. Hughes's statement that βIt is therefore concluded that in addition to the retarding influence of methyl substitution, which operates throughout the series, and may be attributed essentially to the inductive effect, there is a superposed effect, which may in principle enter in all stages of B-substitution, but which assumes real importance only in the case of the neopentyl halide. This effect is believed to be of steric origin2.β
