1.	There are some deposits of nitrates and phosphates in earth's crust. Nitrates are more soluble in water. Nitrates are difficult to reduce under the laboratory conditions but microbes do it easily. Ammonia forms large number of complexes with transition metal ions. Hybridizatioin easily explains the ease of sigma donation capability of NH_(3) and PH_(3). Phosphine is a flammable gas and is prepared from white phosphorus. Among the following, the correct statement is
Answer» Between `NH_(3)` and `PH_(3),NH_(3)` is a better electron donor because the Ione PAIR of electrons occupies spherical s orbital and is LESS directional Between `NH_(3)` and `PH_(3)`, as a better electron donor because the Ione pair of electrons occupies `SP^(3)` orbital and is more directional Between `NH_(3)` and `PH_(3),NH_(3)` is a better electron donor because the Ione pair of electrons occupies `sp^(3)` orbital and is move directional Between `NH_(3)` and `PH_(3),PH_(3)` is a better electron donor because the Ione pair of electrons occupies spherical s orbital and is less directional. Answer :C
