Incorrect statement about $\mathrm{PH}_{3} \mathrm{is}$ :
  1. It is produced by hydrolysis of $\mathrm{Ca}_{3} \mathrm{P}_{2}$.
  2. It gives black ppt. $\left(\mathrm{Cu}_{3} \mathrm{P}_{2}ight)$ with $\mathrm{CuSO}_{4}$ solution.
  3. Spontaneously burns in presence of $\mathrm{P}_{2} \mathrm{H}_{4}$
  4. It does not react with $\mathrm{B}_{2} \mathrm{H}_{6}$.
