On reacting with NaOH, which gives inflammable gas?
Sulphur on boiling with NaOH solution gives
Which reaction gives colloidal solution
The compound which undergoes fastest reaction with aq. NaOH solution is :
A mixture of formaldehyde and benzaldehyde on heating with aqueous NaOH solution gives :
A compound (X) on heating with an excess of NaOH solution gives a gas (Y) which gives white fumes on exposure to HCl. Heating is continued to expel the gas completely. The resultant alkaline solution again liberates the same gas (Y) when heated with Zn powder. However, when the compound (X) is heated alone does not give nitrogen. Identify (X) and (Y).
