## Abstract The rates for the reduction of ketones with sodium borohydride are interpreted in terms of two parameters, both derived from force‐field calculations; __i.e.__ the strain difference between alcohol and ketone (Ξ” strain) and the steric hindrance towards approach of the hydride R. Models
