(Q3) Organic Acids and Esters

Question 1

Organic Acids/Carboxylic Acids

Answer 1

• Functional Group: -COOH (Carboxyl group)
• General Formula: R-COOH

ex. Methanoic Acid/Formic Acid

Question 2

What is created when formaldehyde/Methanal is oxidized?

Answer 2

Formaldehyde/Mathanal oxides to form Formic Acid/Methanoic Acid

Question 3

What is created when Acetaldehyde/Ethanal is oxidized?

Answer 3

Acetaldehyde/Ethanal oxidizes to form Acetic Acid/Ethanoic Acid

Question 4

Creation and Progression of Formaldehyde

Answer 4

• Methanol/Methyl Alcohol and oxygen react (oxidize) to form methanal (formaldehyde)
• Formaldehyde/Mathanal oxides to form Formic Acid/Methanoic Acid

Question 5

Esters

Answer 5

• Formed from the dehydration/removal of water that occurs between a carboxylic acid and alcohol
• General Formula: R-COO-R

Ex. Ethyl Acetate

Question 6

Ethyl Acetate

Answer 6

• An ester derived from ethanol and acetic acid
• A colorless liquid that smells like glue or nail polish

Question 7

Methyl Salicylate/ Oil of Wintergreen

Answer 7

• Ester derived from methanol and salicylic acid
• A natural product of many plants, some called wintergreens (has a minty smell)
