Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. In PCl5, Cl is more electronegative than P, P gets delta+ charge , and hence orbital contraction occurs. NCl5 is not possible because of no vacant d-orbitals. Clearly, N2O5 and the ubiquitous nitrate ion, NO3^-, demonstrate that nitrogen can exist in the +5 oxidation state. Therefore there is no way to arrange five pairs of bonding electrons around a nitrogen atom. Thus, N can not form NCl_5 compound. This function was created in NCL V6.2.1, to complement the isfilepresent function, which now only returns True if the file is present and it is a supported format recognized by addfile . 2139 views Create a VSPER sketch of this cation, and describe it's geometry.
