In this experiment‚ the instructor requested that 4 ml diethyl ether be added to the solution in the conical vial after step 4 to help better see the difference between the organic and aqueous layer. During step 4‚ NaCl(aq) was also available‚ and was used instead of water. The last test involving NaI was not performed. Results A volume of 1.54 ml of

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few. Molecular geometry is associated with the specific orientation of bonding atoms. A careful analysis of electron distributions in orbitals will usually
