Answer 3

a molecule containing one or more double bonde

Question 4

homologous series

Answer 4

a sequence of related chemical compounds that have similar chemical properties but differ in formula by a fixed group of atoms (usually CH2).

members of a homologous series exhibit a trend in physical properties

Question 5

alkanes

Answer 5

a homologous series of saturated hydrocarbons with the general formula CnH2n+2

Question 6

alkenes

Answer 6

a homologous series of unsaturated hydrocarbons with general formula CnH2n

Question 7

isomers

Answer 7

different compounds with the same molecular formula but difference displayed formulae

Question 8

polymer

Answer 8

a substance consisting of huge molecules formed by many small molecules bonding together.

polymers have repeating units in their structures

polymers are commonly called plastics

Question 9

monomers

Answer 9

the small molecules that join together to produce a polymer

Question 10

addition polymer

Answer 10

a type of polymer formed by adding together monomers (usually alkenes).
