There are some deposits of nitrates and phosphates in the earth's crust. Nitrates are more soluble in water. Nitrates are difficult to reduce under laboratory conditions but microbes do it easily. Ammonia forms a large number of complexes with transition metal ions. Hybridisation easily explains the ease of sigma donation capability of `NH_3` and `PH_3`. Phosphine is a flammable gas and is prepared from white phosphorous.
White phosphorous on reaction with `NaOH` gives `PH_3` as one of the products. This is a.

dimerization reaction

B

disproportionation reaciton

C

condensation reaction

D

precipitaion reaction

Text Solution

Verified by Experts

The correct Answer is:
B
It is disproportionation reaction,
`overset0P_(4)+3NaOH+3H_(2)O to 3NaH_(2)overset(5+)PO_(2)+overset(3-)PH_(3)`
