Acetylene does not react with

Given two methods of preparation of acetylene. How does it react with water and Ozone?

Assertion : Acetylene on reacting with sodium gives hydrogen. Reason : sp hybridised carbon atoms of acetylene are considerably electronegative.

Assertion : Acetylene on reacting with sodamide gives sodium acetylide and ammonic. Reason : sp- hybridised carbon atoms of acetylene are considerably electronegative.

Assertion : Acetylene on reacting with sodamide gives sodium acetylide and ammonia. Reason : sp hybridised carbon atoms of acetylene are considerably electronegative .

Acetylene is acidic but it does not react with NaOH or KOH. Give reason.

Acetylene is acidic but it does not react with sodium hydroxide or potassium hydroxide. Give reason.

Acetylene does not form a salt with caustic soda, but readily reacts with NH_(2)^(-) - Why?

How does acetylene gas reacts with (i) chlorine (ii) ammónical cuprous chloride
