Question

Which of the following compounds will violate the octet rule? Answer A:03 Answer B: NCI3 Answer C: CO2 Answer D: NO2

Answer 1

According to octet rule , there must be 8 electrons in the valence shell or an atom.

NO₂ 0 – 0=0 - N c: CO2 o = c=0 NO₂ 30-N=ö Elections around N=7 NOviolates octet sule.

In the Lewis structure of a compound there must be 8 electrons around each atom.

Steps to draw Lewis structure :- 1. Write the chemical symbols of each element involved in the structure. 2. Count the number of lone pairs and bond pairs of electrons on each atom. 3. Single bonds are represented by single line , double bond by double line and triple bond by triple line between the bonded atoms.
