1.	Which of the following is a property of phosphine?(a) It is insoluble in water(b) It is inflammable(c) The solution of phosphine in water decomposes in the presence of light(d) It acts as a Lewis acidI got this question by my college director while I was bunking the class.Question is taken from P-Block Elements in portion P-Block Elements of Chemistry – Class 12
Answer» The correct answer is (C) The solution of PHOSPHINE in WATER decomposes in the presence of light The explanation is: Phosphine is slightly soluble in water and is non-flammable in PURE form. It is a Lewis base and the solution of phosphine in water decomposes in the presence of light giving red phosphorous and HYDROGEN gas.
