Question

Which of the following has been named correctly?

• A. $S_2{O}_3^{2-}$ thiosulphite ion
• B. ${N_3}^{-}$ nitride ion
• C. ${HA{s}_3}^{-2}$ monohydrogenarsenite ion
• D. $H_{2}P{O}_4^{-}$ dihydrogenphosphite ion

Answer 1

The correct option is D $H_{2}P{O}_4^{-}$ dihydrogenphosphite ion

$S_2{O}_3^{2-}$ thiosulphate ion
$N^{3-}$ nitride ion
$HA{s}_3^{-2}$ monohydrogen arsenate ion
$H_{2}P{O}_4^{-}$ dihydrogen phosphite ion
