 Title    The Alkyl Inductive Effect. I. Relations between cr*, q^ and q* for H and Alkyl Groups; <7j Values from the Size and Branching of R  
 Abstract    For alkyl groups it is shown that new inductive substituent constants, a\ (R), can be calculated accurately from previously obtained polar substituent constants, a*(R), from the simple relation a\ (R) = oi (Me) [I-2ct* (R)]. In similar fashion, the two reaction constants are related by qi/q* = a* (H)/ci (Me) = 10.6. Many new o\ values are presented for groups for which no previous estimate has been available. The attentuation of o\ (R) with alkyl size for n-alkyl groups is shown to be a function of the number of C atoms, nc: (TI(R) = —0.137 nc/(2nc + 1). The effect of branching of R is also discussed.
