Answer the following questions about the Lewis structure for the organic molecule CH3CH2CH2CN (see examples in Chapter 10) There are valence electrons. The molecule has single bonds, double bonds, and triple bonds. The three central C atoms on the left have REDS and the shape at each of these is The central C on the right has REDS and the shape is The AENC-N = 0.49 which is only slightly polar and we will consider it to be nonpolar. %3D Since there is only slightly polar covalent bond, the molecule is mostly а.
