There are some deposits of nitrated 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.
Which of the following statement is correct ?

Options

A. Between `NH_(3)` and `PH_(3),NH_(3)` is a better electron donor orbital and is less directional
B. Between `NH_(3)` and `PH_(3),PH_(3)` is a better electron occupies `sp^(3)` orbitals and is more directional
C. Between `NH_(3)` and `PH_(3),NH_(3)` is a better electron donor because the lone pair of electron occupies `sp^(3)` orbital and is more directional
D. Between `NH_(3)` and `PH_(3),PH_(3)` is a better electron dono because the lone pair of electron occupies spherical 's' orbital and is less directional

Answer

C

Explanation

Hybridised orbital are prominent in bonding due to `sp^(3)` hybrid orbital have more directional character than s-orbital.
