Oxalic acid,
H2C2O4,
a poisonous colorless solid, is found in some vegetables such as spinach and rhubarb. It is present in concentrations well below the toxic limit, so you can't use this as a reason to refuse a helping of spinach. The order of atoms in a molecule of oxalic acid is
HO2CCO2H.
(a) How many unshared pairs of electrons are on each of the carbon atoms?
(b) How many unshared pairs of electrons are on each of the oxygen atoms?
Consider lisinopril, a drug used primarily in the treatment of high blood pressure, heart failure, and after heart attacks.
(a) Complete the Lewis structure of lisinopril, showing all valence electrons.
(b) Use the valence-shell electron-pair repulsion (VSEPR) model (Section 3.10) to predict all bond angles in lisinopril.
(c) Which is the most polar bond in lisinopril?
(d) Is lisinopril polar or nonpolar?
(e) Is lisinopril expected to possess resonance (Section 3.9)? Explain why or why not.
(f) Name the various functional groups in lisinopril.
(g) What is the molecular formula of lisinopril?
(h) What intermolecular forces are expected to exist between molecules of lisinopril in close proximity to one another (Section 5.7)?
