## Abstract 300 MHz spectra are obtained for cis‐, and trans‐2‐trlfluoromethyl‐4‐(chloro) methyl‐1, 3‐dioxolanes. A comparative study with other 2, 4‐disubstituted and 2, 2‐bis trifluoromethyl trisubstituted dioxolanes, allows the assignment of each of the H‐5 atoms. From the extracted spectral par
