We present high-resolution Combined Array for Research in Millimeter-Wave Astronomy (CARMA) lambda = 1 mm observations of several molecular species toward Orion-KL. These are the highest spatial and spectral resolution 1 mm observations of these molecules to date. Our observations show that ethyl cyanide [C2H5CN] and vinyl cyanide [C2H3CN] originate from multiple cores near the Orion hot core and IRc7. In addition we show that dimethyl ether [(CH3)(2)O] and methyl formate [HCOOCH3] originate from IRc5 and IRc6 and that acetone [(CH3)(2)CO] originates only from areas where both N-bearing and O-bearing species are present.
