Write a structural and a line-angle formula of propene (C3H6). Write the IUPAC name. On the structure, specify a shape of each carbon
Define detection limit. Does a compound with high molar absorptivity have a higher or lower limit of detection than a compound with low molar absorptivity
calculate which reactant is the limiting reactant. In other words, the formula is CuSO4+ 5H20. Given the limiting reactant above, how much copper, in grams, should be produced by this reaction.
Aldehydes react with KCN and HCN to form cyanohydrins. The nitrile may be further converted to a carboxylic acid or -CH2NH2. Carry out the synthesis of a cynohydrin from cyclopentanecarboxaldehyde and convert it to a carboxylic acid and a -CH2NH2.
