7. Arrange the following acids in the increasing order of their solubility in water: p- CIC6H4COOH, CH3COOH, CH3(CH2)3COOH Click or tap here to enter text.
What is the functional group of propanoic acid? How do we know if it's soluble in water or not using the flowchart that is attached. which test should be performed using the flowchart. Is propanoic acid a ketone, aldehyde, ester or alcohol and how did you know?what would be the most efficient series of solubility and functional group tests that would identify the functional group? Also what could be the sources of error in this experiment? What could occur that would give false positives, false negatives, or incorrect interpretations?

HOW AIR FRESHENERS WORK Some air fresheners just mask bad smells, while others claim to eliminate odors completely. Here. we review the different types of compounds found in air fresheners and how they combat stench. FRAGRANCES ODOR TRAPPING Air freshener aroma compounds mask bad smells. They include terpenes such as limonene and a-pinene. Some people have expressed concern that these can react with ozone to produce formaldehyde, a carcinogen. ODOR NEUTRALIZING Some air fresheners use organic acids, which can react with smelly compounds to break them down to more benign molecules. CITRIC ACID MALEIC ACID LIMONENE E a-PINENE HO но.

5 In the condensation reaction used in Part B, the water molecule is produced when a -OH from the carboxylic acid functional group in one molecule bonds to the proton of an alcohol functional group in the other molecule. Consider the two molecules below and answer the questions that follow. OH HO H₂SO4 a. Circle the -OH of the carboxylic acid group and the proton of the alcohol that combine to form H₂O. b. Recall that oxygen generally participates in two bonds and carbon participates in four. Draw a dotted line between the two atoms in the organic molecules that must bind to each other in order to maintain the typical bonding numbe for all atoms if the circled elements of the H₂O molecule separate from the reactants. c. In the box provided, draw the product formed by bonding the atoms connected by your dotted line.
