Rank each of the following compounds in decreasing order of reactivity towards friedel-crafts alkylation. most reactive = 1; if a compound will not react, rank it as "non" rather than assigning a numerical value. compound a: acetophenone compound b: iodobenzene compound c: benzonitrile compound d: anisole submit answertry another version

1 iodobenzene 2 benzonitrile 3 acetophenone 4 anisole

Explanation:

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

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
