Name Time 4) The study of carbon-containing compounds and their properties is called organic chemistry, Besides carbon atoms, organic compounds also can contain hydrogen, oxygen, and nitrogen atoms (as well as other types of atoms). A common trait of simple organic compounds is to have Lewis structures where all atoms have a formal charge of zero. Consider the following incomplete Lewis structure for an organic compound called histidine (an amino acid), which is one of the building blocks of proteins...

Draw the structure of any organic compound that contains eight carbons, but only has six distinct resonances in its broadband proton-decoupled^13C NMR spectrum. Explain why there are only six, not eight resonances in the^13C NMR spectrum. How many degrees of unsaturation exist for a compound with a formula of C_10H_13O? Show your calculation clearly. List all the common functional groups that are compatible w this molecular formula. C. Which functional groups are present if the compound in Question 6B has...
