This problem has been solved! By looking at the molecule explain why there is such a intermolecular strain using the knowledge of hybridization and bond angles. Then, try SnaPeaks – simply upload your MS/MS data and SnaPeaks will provide what’s in your natural products. Because of their spherical shape, 2s orbitals are smaller, and hold electrons closer and ‘tighter’ to the nucleus, compared to 2p orbitals. The contents of this page can freely be shared if cited as follows: Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms. Question Papers 301. Notice that as the bond order increases the bond length decreases and the bond strength increases. 1-Cyclohexyne is a very strained molecule. Include all hydrogen atoms.
