Answer 2

trigonal pyramidal 109

Question 3

carbon with 1 double and 2 single bonds

Answer 3

trigonal planar 120

Question 4

larger the molecuole

Answer 4

the less polar it will be therefore less soluble

Question 5

alkanes are used

Answer 5

mainly as a fuel source, they undergo combustion reactions which release large amounts of energy

Question 6

alyknes are used as

Answer 6

starting materials to build other materials often in industry or medicine

Question 7

all families are hydrocarbons except

Answer 7

alkanes, alkenes, and alkynes (aliphatic hydrocarbons)

Question 8

alkenes are used as

Answer 8

small alkenes are used as fuel source

are ingredients for making a large variety of plastics

Question 9

carboxylic acids often have

Answer 9

unpleasent odours

Question 10

carboxylic acids often act like

Answer 10

weak bronsted lowry acids. only the h on the oh group can be donated

Question 11

aldehydes and ketones are often used as solvents because

Answer 11

they can dissolve both polar and non polar solutes

Question 12

aldehydes smell

Answer 12

pungent

Question 13

ketones smell

Answer 13

sweet

Question 14

aromatics and cyyclicals have higher melting points then chains

Answer 14

because bond rotation is restricted making molecuole less flexible and easier to stack

Question 15

aromatics often have

Answer 15

strong odours and used as solvents, pesticides and preservatives (DDT)

Question 16

ringed carbons solubility

Answer 16

weak DID’s low solubility

extremely flammable
used as solvents, propellants, and anesthetics

Question 18

amines smell

Answer 18

fishy

Question 19

amines act as

Answer 19

weak bronsted lowry acids the lone pair on the N can accpet a h from an acid

Question 20

alkyl halides were

Answer 20

restricted in 1980 due to depletion of ozone layer

used as solvents, refrigerants and propelents

Answer 22

solids

Question 23

amides are used in

Answer 23

plastic and rubber industries

Question 24

alcohols
