Answer 2

alkanes

Question 3

double bonds

Answer 3

alkenes

Question 4

Triple bond

Answer 4

alkynes

Question 5

are hydrocarbon compounds that only have single bonds in the compounds. ____ are also known as saturated hydrocarbons because additional hydrogen atoms can no longer bond in the compound.

Answer 5

alkanes

Question 6

are hydrocarbons that have one or more carbon-carbon double bonds in their structures.

Answer 6

alkenes

Question 7

contain at least one carbon-carbon triple bond. They have less than the maximum number of hydrogens, that’s why they are classified to be unsaturated.

Answer 7

alkynes

Question 8

Question 13

is formed when carbon or hydrocarbons are burned in limited supply of oxygen. It is a colorless and odorless gas.

Answer 13

carbon monoxide(CO)

Question 14

silent killer

Answer 14

carbon monoxide

Question 15

is a chemical compound composed of one carbon and two oxygen atoms. It is a colorless and odorless

Answer 15

carbon dioxide(CO2)
