💡 Solution & Explanation

Correct option: \(\text{D}\). The correct choice is \(\text{D}\), Propane-1, 2, 3-tricarbonitrile O CH C OH 2 OH. Choose the longest parent chain or ring containing the principal functional group, number it to give the lowest possible locants to multiple bonds, functional groups and substituents, then arrange substituents alphabetically. These IUPAC rules lead to the name shown in the correct option. Recovered question text: 45. IUPAC name will be 2 2 CN CN CN (A) 1, 2, 3-Tricyano propane (B) Propane-1,2,3-trinitrile (C) 1, 2, 3-Cyano propane (D) Propane-1, 2, 3-tricarbonitrile O CH C OH 2 OH
