Concept explainers
Interpretation: Letter (a to e) that best completes new definition of strong base in order to be consistent with old definition of strong base should be determined.
Concept introduction: According to Bronsted-Lowry concept, substance that donates proton is termed as acid while that accepts or gains protons is called base. Species formed after loss of protons from acids are known as their respective conjugate bases whereas conjugate acid is produced by addition of protons to base. Strength of conjugate acids and conjugate bases are inversely related to strengths of their respective bases and acids.
According to Lewis concept, substance that donates electron pair is termed as base while that accepts or gains electron pair is called acid. For example,
According to Arrhenius concept, substances that donate hydrogen ions in solutions are known as acids while bases are substances that release hydroxide ions in solutions.

- Part 2 of 2 Draw the skeletal structure of the product(s) for the Lewis acid-base reaction. Include lone pairs and formal charges (if applicable) on the structures. The Click and drag to start drawing a structure.arrow_forward2. Tetrahydrocannabinolic acid (THCA), the precursor to THC, a psvchoactive: H.. • This molecule is missing eight lone pairs. Add them to the structure above • Check the formal charges of the oxygen atoms above. Do any of them have a non-zero formal charge? If so, add the charges to the appropriate oxygen atoms • THCA is a weak acid. Identify and circle the acidic hydrogen on the above structure • Draw a resonance structure of this molecule belowarrow_forwardO REPRESENTATIONS OF ORGANIC MOLECULES Ranking resonance structures Rank the resonance structures in each row of the table from major to minor.
