Rank substituents in order of their priority when assigning the e or z label to an alkene. i, ch2i , h, ch2ch2cl, f

We assign the priority to an atom or group of atoms based on selection rules

The selection rules are

a) the first priority is given to the group which is attached to double bonded carbon atom with highest atomic number element

so here we will give first priority to I and second to F

b) if same atoms are attached to double bonded carbon atom then the priority is assigned based on the next atom with highest atomic number

here we will give third priority to CH2I

c) after this the priority will be given to CH2CH2Cl

d) the least priority group will be hydrogen [least atomic number]

So the rank will be

I > F > CH2I > CH2CH2Cl> H

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

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
