Just find oxidation number the negative charge will be out of coordination sphere to make molecule neutral
Then +3 will come on P so total +9 so minus 9 will go out
And on N there will be +1 so total +3 so minus 3 will go out
Am i right ? I think answer should be D but ans is B
No negative and postive charge will be equal nd opposite
How you guys are finding oxidation number NH3 is a neutral molecule and CO is also. Not sure about PF3 but i thought it should be neutral as well so oxidation number should be 0 in all cases.
Oh sorry by mistake but i am also confused what should be oxidation number of PF3
@Gaurav_2020_3 why not +3 of PF3
