5.) a.) b.) Ethyne (C₂H₂) has the shortest C-to-C bond because there is a triple bond between the two C’s. The shorter the bond‚ the smaller the distance between the two bonded atoms‚ a single bond has the largest distance between two bonded atoms. c.) i.) trigonal planar ii.) pyramidal d.) This is not true because the bonds described are intramolecular forces‚ C-H‚ C-O‚ O-H‚ which are not affected by boiling. When boiling occurs‚ added energy overpowers intermolecular forces‚ not
