Which molecule could have an expanded octet? hno2 h2co3 h3po4? - 7001943 Answer to Which molecule could have an expanded octet? (a) H2CO3(b) H3PO4(c) HNO2. Lewis structure of H2CO3? SAVE ... that doesnt obey the octet rule. Nitric oxide has the formula NO. The total number of valence electrons is 5+6=11. Therefore, no matter how electrons are shared between the nitrogen and oxygen atoms, there is no way for nitrogen to have an octet. It will have seven electrons, assuming that the oxygen atom does satisfy the octet. Expanded Octet in Lewis Structures Expanded octet refers to the Lewis structures where the central atom ends up with more than an octet, such as in PCl 5 or XeF 4. In drawing the Lewis structure for PCl 5 , there is a total Which molecule could have an expanded octet? a) H2CO3 b) H3PO4 c) HNO2 Some central atoms may have more than an octet ... Only atoms in rows below the 2nd row can have expanded ... HNO3, CO32-, H2CO3, H2C2O4, C2O42-, H3PO4 When we have an H (or H2) in front of a polyatomic molecule (like CO3, SO4, NO2, etc.) we know that it's an acid. This means that the Hydrogen atoms will be attached to the outside of the oxygen molecules. Not knowing this information makes it very difficult to draw the Lewis structure for H2CO3. For the H2CO3 Lewis structure, Which molecule could have an expanded octet? a) H2CO3 b) H3PO4 c) HNO2 2. Write Lewis strtucture for XeF2. 3. Write Lewis structure for each molecule shown below: a) ClO2 b) BeCl2 19 Chemistry 101 Chapter 9 BOND ENERGY The bond energy of a chemical bond is the energy required to break 1 mol of the bond in the gas phase.
