Since we only have a weak nucleophile so activate the nitrile, protonation makes it more electrophilic. Step 2: The water O functions as the nucleophile attacking the electrophilic C in the C≡N, with the electrons moving towards the positive center. Step 3: An acid/base reaction. skyrim se flying mod collision

Stephen aldehyde synthesis, a named reaction in chemistry, was invented by Henry Stephen (OBE/MBE). This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl2), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH2] Cl ) with water (H2O). During the synthesis, ammonium chloride is also produced. WebABSTRACT: In the present work, undoped (SnO2) and fluorine-doped tin oxide (FTO) thin films were prepared by sol-gel process using a solution composed of (SnCl2, H2O), (NH4F), and ethanol mixture. The fluorine concentration effect on structural, optical and electrical properties of SnO2 films is investigated.
