accptable? erroneous Explanation: Sorry, this does not make sense. N,N in the first term means that two functions (i.e., functional groups such as OH, Cl, methyl, etc.) are connected through N atom to the benzene ring. However, they are not noticed before the first term. In the second term there are only two functions: hydroxy-groups, so only two figures are possible in the beginning of the term. |
