A novel R-configuration or S-configuration optically active alcohol of the formula (1), CF.sub.3 C*H(OH)(CH.sub.2).sub.m OCH.sub.2 CH.sub.n F.sub.3-n(1) wherein C* is an asymmetric carbon atom, m is an integer of 2 to 7, and n is an integer of 0 to 2, and a process for the production of the optically active alcohol from a monohalogenated alkyl having a fluoroalkoxy group at a terminal. The novel optically active alcohol, provided by the present invention, having a trifluoromethyl group on an asymmetric carbon atom and a fluoroalkoxy group at a terminal, is useful as a raw material for the production of a novel liquid crystal compound.
