a) sp3 in bromine and s in hydrogen.

b) sp3 in both iodine atoms.

c) sp3 in carbon and sp3 in fluorine.

d) sp in carbon and s in hydrogen.

e) sp2 in the carbon and sp3 in chlorine.

f) sp3 in the carbon with three hydrogens and sp2 in the carboxyl carbon.

g) sp2 in the carboxyl carbon and sp3 in the oxygen.

Hint: refer to the electron domain geometry around the atom in question.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
