Use lowercase letters and do not use spaces.] *       A- 4-carboxy-2-propylaniline       B- 2-amino-1-propyl-5-benzoic acid       C- 4-amino-3-propylbenzoic acid       D- 4-amino-3-propylbenzenecarboxylic acid       E- 1-amino-2-propyl-4-benzoic acid

Identify the functional groups

2. A student named a compound as 6-methyl-6-ethylhept-1-en-5-one. Even though one can draw a correct structure based on that name, the name itself is incorrect according to the IUPAC naming conventions. Draw a structure for the compound (based on the above name), and then name the compound correctly. Structure Correct Name

Give the IUPAC name for the compound bellow: Br Br 6-methyl-1,4-dibromobenzene 1,4-dibromo-2-methylbenzene 1-methyl-2,5-dibromobenzene 2,5-dibromo-4-methylbenzene

1.Draw a structure that corresponds to the incorrectly named: 6-tert-butyl-3-isopropylhexane. 1b. Rename the compound above according to the IUPAC rules. 1c. Draw a circle around every methine (3o) carbon and a square around every 4o carbon. How many 1o and 2o carbons arepresent?

for each of the following reactions labeled (a,b,c,d) write the name of the functional group as well as the correct name for the organic molecule that should appear where the question mark is. You must correctly name the functional group as well as name the structure for each question mark that appears.

Match each of the following definitions to the alphabetical label provided under this chemical name: 3-bromo-2-methyl-3-heptanol Ав с D E F G The letter that indicates that there are 7 carbons in the longest carbon chain: The letter that indicates which carbon the halogen substituent is attached to: The letter that indicates that an alcohol group is attached to the molecule: The letter that indicates which carbon the hydrocarbon branch is attached to: The letter that indicates which carbon the alcohol substituent is attached to: The letter that indicates that the hydrocarbon branch has only 1 carbon:

1. Most margarines have been hydrogenated to maintain a soft, homogeneous mixture. While the product is easy to spread, this has made the product an unhealthy choice. A hydrogenation reaction is used to convert an alkene to an alkane. a carboxylic acid to an aldehyde. an alkene to a ketone an aromatic hydrocarbon to a linear hydrocarbon

Which structure contains the alkyne functional group? нн -C-C- H H R1 R3 R2 R4 R-C=C-R' Н-с-о-н I-C-H
