Question

Write the systematic IUPAC names of the following compound:

Accepted Answer

Rules to name a compound with multiple functional groups:

1. When a compound has more than one functional group, the group which determines the class of the compound is referred to as the principal group and forms the suffix. The remaining groups are treated as substituents. The functional group placed higher in the table takes precedence over the others below. The longest continuous chain should contain maximum number of functional groups.

2. The principal chain of the polyfunctional compound must be numbered in such a way that the principal functional group gets the lowest possible number followed by double bond, triple bond and substituents.

3. The substituents must be placed in alphabetical order before the word root. When two substituents occupy identical positions from either end of the principal chain, then the lowest number must be given to the substituent which comes first in the alphabetical order.

Hence, the IUPAC name of the given compound is: But-2-ene-1,4-dioic acid
