Multiple Bonds (Section)
Consider the Lewis structure shown below.
(a) Does the Lewis structure depict a neutral molecule or an ion? If it is an ion, what is the charge on the ion? (b) What hybridization is exhibited by each of the carbon atoms? (c) Are there multiple equivalent resonance structures for the species? (d) Which of the atoms in the species have pπ orbitals? (e) How many electrons are in the π system of the species?
Week 1 Notes Ch. 1&2 Ch. 1 The Chemical Basis of Life What is Biochemistry explains life at the molecular level, using chemistry terms to describe living things. Explains the whole by breaking it into smaller parts (i.e. levels of organization: organism is the whole and organ, cell, organelle, molecules are the smaller parts) Questions of Biochemistry o What are living things made of o How do organisms gain and use energy o How does an organism maintain its identity across generations Biological Molecules Elements found in a living system: C, N, O, H are the main elements Ca, P, K, S, Cl, Na, Mg Bond energies of organic compounds range from ~350-490 kJ/mol o Life requires a certain leve
