- Acridine is a heterocyclic aromatic compound obtained from coal tar that is used in the synthesis of dyes. The molecular formula of acridine is C13H9N, and its ring system is analogous to that of anthracene except that one CH group has been replaced by N. The two most stable resonance structures of acridine are equivalent to each other, and both contain a pyridine-like structural unit. Write a structural formula for acridine.arrow_forwardCompound X (structure shown below) has a molecular formula C5H1o and reacts with H2/Pt to give compound Y, C5H12. What is the name of the reaction involved to produce Compound Y?

- Compounds A and B are isomers having molecular formula C5H12. Heating A with Cl2 gives a single product of monohalogenation, whereas heating B under the same conditions forms three constitutional isomers. What are thestructures of A and B?arrow_forwardA compound has the molecular formula C5H1002. Its IR spectrum shows a strong absorption band near 1740 cm1. Its 'H NMR spectrum consists of two singlets at Õ 1.2 and o 3.6. Which is the most likely structure of the compound?arrow_forwardThree compounds, A, B, and C, have the same molecular formula, C5H6. In the presence of a platinum catalyst, all three compounds absorb 3 molar equivalents of hydrogen and yield pentane. Compounds B and C give a precipitate when treated with ammoniacal silver nitrate; compound A give no reaction. Compounds A and B show an absorption maximum near 250 nm. Compound C shows no absorption maximum beyond 200 nm. Propose a structure for A, B, and C.arrow_forward
- Assume that you have samples of the following two compounds, both with formula C7H8O. Both compounds dissolve in ether, but only one of the two dissolves in aqueous NaOH. How could you use this information to distinguish between them?arrow_forwardCompound A (C3H17B1) undergo dehydrohalogenation to produce major compound B. Compound C was formed when compound B undergo halogenation in room temperature. Compound B undergo halogenation in aqueous solution to form compound D. Compound B undergo hydrohalogenation in the presence of H202 to form Compound E. Compound B undergo oxidation with hot acidified KMN04 to produce compound F and Compound G. Compound H was produced when Compound B react with cold KMN04. Compound B undergo ozonolysis to form Compound I and Compound J. Compound K was formed when compound B reacted with hydrogen in the presence of platinum. Compound A reacted with sodium hydroxide to form compound L. Compound M was produced when compound A reacted with ammonia in ethanol while compound N was formed when compound A reacted with sodium cyanide. Reaction X happened when compound K reacted with bromine in the presences of UV light. a) Identify the possible structural formulae for compound A to N.
