Aldehydes and ketones will not form crystalline derivatives with
(a) sodium bisulphite
(b) phenyl hydrazine
(c) semicarbazide hydrochloride
(d) dihydrogen sodium phosphate
(d) Dihydrogen sodium phosphate (NaH2PO4) does not react with aldehydes and ketones because NaH2PO4 does not have any lone pair of electron on phosphorus atom, so it cannot act as a nucleophile.
