A) \[N{{H}_{3}}<P{{H}_{3}}<As{{H}_{3}}\]
B) \[As{{H}_{3}}<P{{H}_{3}}<N{{H}_{3}}\]
C) \[P{{H}_{3}}<As{{H}_{3}}<N{{H}_{3}}\]
D) \[N{{H}_{3}}<As{{H}_{3}}<P{{H}_{3}}\]
E) \[As{{H}_{3}}<N{{H}_{3}}<P{{H}_{3}}\]
Correct Answer: C
Solution :
Order of increasing enthalpy of vaporisation is \[P{{H}_{3}}<As{{H}_{3}}<N{{H}_{3}}\] The enthalpy of \[N{{H}_{3}}\] is higher due to the H-bonding.You need to login to perform this action.
