Concept explainers
Interpretation:
The resonance structures of thiocyanate ion
Concept introduction:
For many molecules, it is impossible to explain all properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn to explain the properties. Such structures of a compound are called resonating structures and the phenomenon is called resonance.
Due to their attraction towards electrons, the ions and the molecules acquire some charge which is called formal charge.
Formal charge is given by:
Total number of valence electrons in a free

- Some plant fertilizer compounds are HNO3, H2SO4, H3PO4, NH4NO3, and K2CO3. Which of these compounds contain both ionic and covalent bonds? (Select all that apply.)arrow_forwardexplain difference between non-polar and polar covalent compound along with example of this type of bond in clear handwritten answer!arrow_forwardT1 Choose correct answer: Find the molecule that does not octet principle.

- Which of the following are ionic compounds? Select all that apply.arrow_forwardIndicate the formal charge on each atom in the following structure. Show calculations.arrow_forwardDraw 2 valid Lewis structures for xenon trisulfide. Clearly label the structures A and B. For structure A, draw a Lewis structure where all atoms obey the octet rule. For structure B, minimize the formal charges. In both structures, show all bonds and lone pairs of electrons and include any non-zero formal charges on the appropriate atom(s).arrow_forward
- Formal charge both sign and magnitudearrow_forwardI am wondering why there is a need for resoance structures if the molecule already has a neutral charge. Wouldn't these all be insignificant resonance structures (as there is unnecessary charge separation)? Perhaps they are only depicting these structures for the purpose of showing high/low electron density (which was what the question was asking for)? 1 picture shows answer, another shows problem (it is (b)).arrow_forwardI got the net charge -1 but the system shows it wrong. The formula I used: Formal charge= Valence electron-(bonding electrons +individual lone pair)arrow_forward
