For each of the given solution, the pH of the solution is to be determined from the given pOH values and based on the pH value, each solution is to be classified as acidic, basic or neutral. Concept introduction: The sum of pH and pOH in a solution is always equals to 14 at a constant temperature. At 25 ° C , mathematically it can be shown as follows: pH + pOH = 14 .0 The pH scale is used to classify whether the solution is acidic or basic. The three points for the solution are as follows: The solution with pH value less than 7 is acidic. The solution with pH value greater than 7 is basic. If the solution with pH equals to 7 is neutral.

Concept introduction:
The sum of pH and pOH in a solution is always equals to 14 at a constant temperature. At 25°C, mathematically it can be shown as follows:
pH+pOH=14.0
The pH scale is used to classify whether the solution is acidic or basic. The three points for the solution are as follows:
The solution with pH value less than 7 is acidic.
The solution with pH value greater than 7 is basic.

6) The synthesis generates allethrolone that exhibits high insect toxicity but low mammalian toxicity. They are used in pet
shampoo, human lice shampoo, and industrial sprays for insects and mosquitos. Propose detailed mechanistic steps to
generate the allethrolone label the different types of reagents (Grignard, acid/base protonation, acid/base deprotonation,
reduction, oxidation, witting, aldol condensation, Robinson annulation, etc.)
