Draw the structures for the following molecules (show all lone pairs): a) acrylonitrile, c3h3n, which contains a carbon-carbon double bond and a carbon-nitrogen triple bond. b) ethyl methyl ether, c3h8o, which contains an oxygen atom bonded to two carbons. c) cyclohexene, c6h10, which contains a ring of six atoms and one carbon-carbon double bond. d) determine the hybridization, the shape, the bond angle and the polarity of each of the structures.
