Question

which ranking of acid strength below is incorrect?

A. HBrO3<HClO3

B. H3PO4>HPO4^2-

C. HCl<HBr

D. HNO3<HNO2

E. H2S>PH3

Answer 1

Date: Ice being more electronegative than Br it I pulls the election of in Hydrogen more strongly and Hence has a higher tendency. to release Ht unit o Hence bin HUO, HBr Or - 1 Mood . Hoop? tant li ution on Since Hence no on H nó do 4Po? is conjugate base of B004 113 POq is more acidic HPO > APO HO итто — HBO HA + Br- Since the Boo is more polarisable than ces Hence Bre is more stable ! Since Bro and le are conjugate base of MBY and He and more stable conjugate base is mose acidic so - HBr 7 hle HNO - Notho HNO - No the

Since No is more stable than No, because no has more Cannonical structure thon Ngon More stable the coryugate base more acidic the compound is - 1 Henu - HNO 7 HNO₂ T PLS > PH₂ Sinu H is attached to more elite electronegative in HS than in the PH₂ Hence H₂S is more acidic Hence the because correct the give option order is is @ inconsect.
