polymers and life

Question 1

what is a polymer

Answer 1

a polymer is a large molecule made with repeating units called monomers

Question 2

what are the two types of polymer

Answer 2

addition polymer and condensation polymer

Question 3

carboxylic acid functional group

Answer 3

COOH

Question 4

what atoms are the partial charges of a carboxylic acid on

Answer 4

partially negative charge on oxygen, partially positive charge on carbon (of COOH group)

Question 5

naming carboxylic acids

Answer 5

parent alkane + replace the “e” with “-oic acid”

Question 6

general formula of carboxylic acids

Answer 6

Cn H2n+1 COOH

Question 7

carboxylic acid solubility

Answer 7

carboxylic acids are soluble in water due to hydrogen bonding between the partially positive H and partially negative O in the COOH group and a water molecule

Question 8

carboxylic acid solubility trends

Answer 8

as carboxylic acids get longer, solubility decreases

Question 9

carboxylic acid acidic properties

Answer 9

carboxylic acids are weak acids, but the strongest organic acids

Question 10

test for carboxylic acids

Answer 10

use sodium carbonate Na2CO3
carboxylic acid + sodium carbonate –> salt + water + carbon dioxide

Question 11

carboxylic acid reaction with metal

Answer 11

–> salt + hydrogen

Question 12

carboxylic acid reaction with base

Answer 12

–> salt + water

Question 13

weak acid definition

Answer 13

acids that only partially ionise in solution (in a reversible reaction)

Question 14

examples of carbonyl compounds

Answer 14

carbonyl compounds are ketones + aldehydes only
