Compound A, C9H12, undergoes nitration to give 3 products. The 1H NMR spectrum of A shows a complex three-proton multiplet at 6.92-6.99 δ and a nine-proton singlet at 2.34 δ. What is the structure of A? You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. In cases where there is more than one answer, just draw one.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

the correct answer would be d. hope this !

ugh fiel iente of insistí is did kiwis jaj
