Which formula/name pair is incorrect? Mg3N2 magnesium nitride Mn(NO3)2 manganese(II) nitrate Mn(NO2)2 manganese(II) nitrite Mg(NO3)2 magnesium nitrate Mg(MnO4)2 magnesium permanganate

Transcript

00:01 Which formula name pair is incorrect so first we have given m g 3 and 2 the name is magnesium nitrite so actually this is the incorrect because the name actually the name of this compound is magnesium nitrite magnesium nitrite because in this we have magnesium having two plus ion and nitride that is n3 minus ion so the actual formula of this is m g 3 and 2 the formula is basically the correct but the name is incorrect the correct name is magnesium nitrate then we have mn no 3 twice the compound formula the name of this compound is man mannes to nitrate right because we have man o't know 3 twice the compound the compound is manganese 2 nitrate right because we have man we have this no3 minus ion that is known as nitrate ion and in this case the manganese oxidation state is a plus 2 then we have mn.

01:07 No2 twice so that is known as mannice to nitrite so first of all we see what is the formula of nitrite right so we have nitrite ion right so we no 2 minus so this is known as nitrite ion so this is the formula manganese 2 nitrite and this is the correct formula because the oxidation state of manganese here is plus 2 so this is also correct this is also correct then we have mg.

01:51 No 3 twice that is known as magnesium nitrate so this is known as magnesium nitrate or we can also call it as the magnesium to nitrate why because in this case also this magnesium having charge is plus two but definitely the group two element magnesium always carry a charge plus two when it is attached with some of attached with some compound so we have magnesium nitrate or magnesium to nitrate so we have magnesium to nitrate so so both of these are correct right then we have m g mn o four twice this is known as magnesium per magnet right so this is also correct the compound name and formula is correct and in this case mn o4 minus that is known as per manate ion this is known as per magnet ion right so this is also correct so in this ocean we have to identify the formula or name pair that is incorrect...
