Thiocyanic acid (HSCN) is an inorganic acid (pKa = 1.1 at 25 °C) that can be classified as “strong” largely due to resonance stabilization of its conjugate base, thiocyanate (SCN– ). In the space provided below, draw Lewis electron dot structures of SCN- and all of its important resonance forms.
Give a clear handwritten answer with explanation
Consider the acid-base reaction between iodoethane (CH3CH2I) and hydroxide (-OH). CH3CH2I + OH- --> CH3CH2OH + l- Use the table of bond energies to estimate the change in enthalpy (∆H in kJ/mol) for this reaction. Think about the bonds that are broken and that are formed. This reaction is endothermic, exothermic or energy neutral Using your calculation, what can you say about the strengths of the bonds? -The bonds before the reaction are stronger than the bonds after the reaction. -The bonds after the reaction are stronger than the bonds before the reaction. or -The bonds before and after the reaction are equivalent in strength.

If A H;º is a positive number then that molecule has less chemical potential energy stored in its' bonds than the elemnets it was formed from. that molecule has more chemical potential energy stored in its' bonds than the elemnets it was formed from. that molecule has the same amount of chemical potential energy stored in its' bonds as the elemnets it was formed from.
CO, CO₂, CH3OH, and CO32- all contain carbon-oxygen bonds. Draw Lewis structures for these molecules and ions. Given that double bonds are stronger than single bonds and triple bonds are stronger than double bonds, rank the four species in order of increasing CO bond strength. Weakest: Strongest:
