Draw the following functional groups. You can use "R" in the structure (Example: RCCR): Aromatic Alcohol Ether Ketone Aldehyde; label the carbonyl group Carboxylic acid

Briefly, but clearly, explain why the –OH hydrogen in acetic acid (CH3CO2H) is more acidic than in ethanol (C2H5OH).

Give IUPAC names for the following substances:

The amines are organic weak bases which are nitrogen-containing. In the early days of organic chemistry, basic amines derived from natural sources were known as “vegetable alkali”, but they are now referred to as alkaloids. The study of alkaloids provided much of the growth of organic chemistry, phytochemistry and natural products chemistry. It remains a fascinating area of research. Please search for one naturally occurring alkaloid and provide  the following: Name of the alkaloid and show its structure. Identify using arrows the polar bonds in the structure Species from where it was isolated What was the use of this alkaloid in plants (if any)? What are the pharmacological, medicinal, or environmental uses or applications of this alkaloid (if any)?

Circle the functional groups present in these compounds and identify them.

Which of the following pairs (carboxylic acid: use) is correct? glycolic acid : sugar cane alpha-hydroxy acids : loosening of the epidermis tretinoin : severe acne lactic acid: sour milk

I know there is: 1. Carboxylic group 2. Ester. 3. Ortho-disubstituted phenyl. But my answer is still partial.

Draw the skeletal structures of: phenyl benzoate, benanilide, benzoic acid, and 2-napthaldehyde and identify the carbonyl-containing functional group.

Write structures and describe thephysical properties of carboxylic acids

Write the products of the reaction of diphenhydramine (a base) with the acid HCI shown below. H COCH₂CH₂NCH3 + HC1 CH3 Consider the chemical reaction from the previous question. Are the reactants or products more soluble in water? Briefly explain.
