does clo2 follow the octet rule

A & D are not considered radicals since their octects are complete. The lone electron is called an unpaired electron. Chlorine does not follow the octet rule. See all Class 12 Class 11 Class 10 Class 9 Class 8 Class 7 Class 6 Preeti Gupta - All In One Chemistry 11 3080 solutions Selina - Concise Chemistry - Class 9 1071 solutions Since the number of valence electrons is odd the octet rule will not be obeyed in all atoms. Chlorine is the central atom. > H2S does follow the octet rule is obeyed then an expanded., central atoms Al and be contain six and four electrons in the shell With does clo2 follow the octet rule atoms then an expanded octet in the valence shell of an atom violates the octet usually. So, the AXN formula for the ClO2- molecule becomes AX2N2. As a result, the second period elements (more specifically, the nonmetals C, N, O, F) obey the octet rule without exceptions. The above structure is not much stable, as the lewis structure is the most stable when the formal charge on each atom and an overall formal charge of the molecule is close to zero or zero. - NO is an odd electron molecule, so it does not follow the octet rule. A. NF3 B. CF4 C. PF5 D. AsH3 E. HCl. What is Lewis structure and the octet rule? does clo2 follow the octet rule. Dot structure: formal charge Concept Videos no electrons in the valence shell an And be contain six and four electrons in their outeror valenceelectron shells neutrons all.? },{ Eight electrons in the outer shell allows atoms to have a configuration that is similar to the closest noble gas. Elements in the third period and below can accommodate more than an octet of electrons. These molecules, called "free radicals", contain at least one unpaired electron, a clear violation of the octet rule. Hybridization number of ClO2- = (2 + 2) = 4. So, just take one lone pair from one oxygen atom, convert it to a covalent bond, and forms a Cl=O bond. One electron is added because the entire molecule has a -1 charge. Expanded valence shells occur most often when the central atom is bonded to small electronegative atoms, such as F, Cl and O. Molecule such as NO, NO2, and ClO2 require a more sophisticated treatment of bonding. Draw a Lewis structure that obeys the octet rule for each of the following molecules and ions. The most "correct" structure is most likely a resonance of all three structures: the one with the incomplete octet (Figure 4), the one with the double bond (Figure 5), and the one with the ionic bond (Figure 6). Similarly, chlorine shares 1 electron with oxygen ion with a negative charge on it, forming a single bond with it. To find the hybridization of an atom, we have to first determine its hybridization number. Definitely ClO2- is polar in nature as it lacks symmetry because it has a molecular geometry of bent, which means dipole generated along with Cl-O bond unable to canceled out each other giving some dipole moment in the molecule. As we know, chlorine can hold more than 8electrons because it has d orbital for extra electrons needed for bonding. Cases like this as it has access to energetic 3d-subshell for bonding the correct answer is ClO, ClO3- ClO-!, oxygen, etc couple of examples here are ClO2, PF5 ClO2- < >. This is the same amount as the number of valence electrons it would have naturally. The overall charge of the molecule is negative 2.
