1. Structurecyclohexane cyclohexene : 1. Structurecyclohexane cyclohexene Or Or
Table: 2-7 : Table: 2-7
Question 1 - 5 : Question 1 - 5 1. Insoluble because they are non-polar. Water is polar. Like-dissolves-like.
2. Alkanes: unreactive, Alkenes: most
3. A double bond has both
4. Weaker, projects outward
5. a) addition
b) it was the (acid) catalyst
c) accelerates a reaction without being used up
5 d) Cyclohexene + H2SO4 + H2O : 5 d) Cyclohexene + H2SO4 + H2O cyclohexanol e) Found in water because it has a polar moiety (it is polar)
f) cyclohexanol (the product / the one to the right)
6 a-d: Cyclohexene + Br2 : 6 a-d: Cyclohexene + Br2 a) Orange
b) Addition
c) d) Bromine was used up (disappeared)
