What is the covelency of N2O5?

Posted by Naresh Vishwakarma 7 years, 9 months ago

CBSE > Class 12 > Chemistry

2 answers

Nishtha Pandya 7 years, 9 months ago

Arrey Covalency is the maximum number of orbital available for sharing of electrons. In N2O5 the maximum number of Orbitals of Nitrogen atoms available are 4 and they are 2S, 2Px,2Py,2Pz. Hence covalency of Nitrogen in N2O5 is 4. since in N2O5 the oxidation state of Nitrogen is +5, therefore it means it has utilised all the two electrons availalbe in 2S and all the three electrons availble in 2Px,2Py,2Pz therefore since total of 04 orbital are involved in the formation of N2O5 so covalency is 4

Ruby Bajwa 7 years, 9 months ago

N has covalency of 4 in N2O5

Mtlb apun Japanese bak raha tha or apun ko pata v nhi ???

Nishtha Pandya 7 years, 9 months ago

The particles of solids are close packed and can only oscillate about their fixed positions. These properties make solids rigid. As their intermolecular forces are strong

Jin Kazama 7 years, 9 months ago

Bcz. their particle can't move just vibrate on their mean position thats why they posses rigidity ???
