Concept explainers

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Using Zaitsev's rule, choose the most stable alkene among the following. Draw out the structures of each of the options then select the correct answer. Recall that Zaitsev's Rule is about alkene stability. The trend for this is similar to the trend for carbocation stability. Either more or fewer groups on the alkene (and the carbocation) make it more stable. This question is wanting you to remember if it's more or fewer. A) 1,2-dimethylcyclohexene B) 1,6-dimethylcyclohexene C) cis-3,4-dimethylcyclohexene D) They are all of equal stability according to Zaitsev's rule. Provide the major dehydration product of the following reaction. Recall which of the four substitution and elimination reactions a dehydration is. Before you do your S# or EF mechanism, remember what heteroatoms do in the presence of an acid (aka-the-OH is a bad leaving group, but protonating it might turn it into a good one). Don't forget to apply the concept from the previous question. OH Ht A
