3-Chlorocyclopropene, on treatment with AgBF4, gives a precipitate of AgCl and a stable solution of a product that shows a single 1H absorption at 11.04 ppm. What is a likely structure for the product?

Explanation:

NB: please check attached picture for the drawings.

Chemical shift occurs as a result of shielding and de-shielding which causes the position of the NMR signals to shift. And, the shifts are caused by the involvement of electrons in chemical bonds. Chemical shifts are measured in Hertz that is, cycles per second. The standard compound used for this purpose is tetramethylsilane.

Looking at the question, 3-Chlorocyclopropene is reacted with AgBF4 and it gives precipitate of AgCl and a stable solution of a product. The question now says that the product shows a single 1H absorption at 11.04 ppm.

The Nuclear Magnetic Resonance (NMR) spectroscopy, H'NMR which is 11.04 ppm indicates aromaticity. And one single 1H equal atoms of hydrogen is because of the Resonance effect.
