Answer the question on the basis of the passage given below: 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 metals. Hybridization easily explains the ease of sigma donation of \(NH_3\) and \(PH_3\). Phosphine is an inflammable gas, it is prepared from white phosphorus. |
\(PH_3\) is a better reducing agent than \(NH_3\) because: |
\(PH_3\) can give its lone pair of electron easily Bond dissociation enthalpy of \(P-H\) is low Bond dissociation enthalpy of \(P-H\) is high \(PH_3\) is tetrahedral in shape |
Bond dissociation enthalpy of \(P-H\) is low |
The correct answer is option 2. Bond dissociation enthalpy of \(P-H\) is low. |
