A) high \[{{\Delta }_{a}}H\] value of dihydrogen do not favour the formation of \[P{{H}_{5}}\]
B) \[{{\Delta }_{eg}}H\] value of hydrogen do not favour the formation of \[P{{H}_{5}}\]
C) Both (a) and (b) are correct
D) None of the above
Correct Answer: C
Solution :
Although phosphorus exhibits \[+3\] and \[+5\] oxidation states, it cannot form \[P{{H}_{5}}\]. Besides some other considerations, high \[{{\Delta }_{a}}H\] value of dihydrogen and \[{{\Delta }_{eq}}H\] value of hydrogen do not favour to exhibit the highest oxidation state of P and consequently the formation of \[P{{H}_{5}}\].You need to login to perform this action.
