could someone explain this easily how to use some tricks to learn how to reads these?

What is the hydrogenation of the following reaction in the presence of nick Write it as reactants products with the appropriate reaction conditions. What is the acid catalyzed hydration of the following reaction? Write it as reactants products with the appropriate reaction conditions. Definitely draw all substituents on reference sheet (I will show you). Should be able to choose the correct structure when given the name. Should know CnH2n+2, CnH2n. CnH2n-2 formulas and to what structure it applies. Will need to name one structure with either a phenol, analine, toluene, or benzene as the parent. S What is the IUPAC name of the following structure? Br What is the IUPAC name of the following structure? What is the IUPAC name of the following structure? Please note that the I is an iodine. What is the molecular formula of the following structure? S HN N
