Question

Hey mate Explain Properties of phosphine ???​

Answer 1

PHOSPHINE :-

Phosphine is a chemical which belongs to the group of organophosphorus compounds. He obtained phosphine by supplying heat to phosphorous in an aqueous solution of potassium carbonate. Chemical formula of this compound is PH3.

Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3

Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3Ca3P2 + 6HCl → 3CaCl2 + 2PH3

Properties of Phosphine :-

1) it is a colorless gas having a rotten fish smell.

t is a colorless gas having a rotten fish smell.It is highly poisonous gas.

2)PH3 is sparingly soluble in water and soluble in organic solvents.

3)PH3 acts as a Lewis base by donating its lone pair of electrons when it reacts with hydrogen iodide.

Hope it helps u

Answer 2

Answer:

mark me as brainliest if this is correct plssssss

Explanation:

Phosphines are colourless gas. It has a characteristic smell like that of a spoiled fish. It is an exceedingly noxious gas. PH3 is sparingly dissolvable in water. However, it can dissolve in natural solvents. PH3 acts as a Lewis base by giving away its lone pair of electrons by reacting with hydrogen iodide. Under typical conditions, it is a non-ignitable gas. But, when you warm it, it bursts into flames, forming phosphoric acid. It explodes violently when we expose it to oxidising agents.
