2. A compound gives no reaction on the silver nitrate test, a positive on the 2,4-DNP test, a negative on the Tollens test, and a negative on the bromination test. What is the compound type?

A compound gives no reaction on the silver nitrate test( it was hexane), a positive on 2,4-dnp test(Acetone and butanal), a negative test on the tollens test(acetone), and a negative on brominating test(hexane). what is the compound type?

An explanation would be greatly appreciated because I find NMR very tricky for some reason. Thank you!

The ¹³C-NMR spectrum shown is that of a compound withformula C₆H₁₀O₂.This compound has an IR absorption at 1716cm^-1.
The compound gives a negative Tollen's test (chapter 21)and a negative iodoform reaction (chapter 16).
Propose a structure.
