ends in -al
aldehyde (CHO)
ends in -one
carbonyl group (CO)
an alkane contains what type of bonds?
single
an alkene contains what type of bonds?
at least one double
an alkyne contains what type of bonds?
at least one triple bond
an arene contains what type of bonds?
benzene ring
ester
COO
general formula of alkanes
C(n)H(2n+2)
general formula of alkenes
C(n)H(2n) (only applies to structures with 1 double bond)
general formula of alkynes
C(n)H(2n-2)
F name
fluoro
Cl name
chloro
Br name
bromo
I
iodo
complete combustion of alkanes/enes/ynes/ alcohols produces
CO2 + H2O
Reaction of methane with Cl2 - initiation
UV splits bond between CL2
End up with CL• + CL• (chlorine radicals)
Reaction of methane with Cl2 - propagation
Reaction continues
Eg. CL• + CH4 → CH3• + HCL
Reaction not yet complete because one of the products is a free radical
Reaction of methane with Cl2 - Termination
Two radicals make a product with no radicals
Eg. CH3• + CH3• → CH3CH3 (ethane)
dichromate solution formula:
Cr2O7-
oxidation of alcohols means
heat with acidified potassium dichromate solution
Dichromate is _____, when warmed with acid turns _____
orange, green
Oxidation of primary alcohol
–> aldehyde –> carboxylic acid
Oxidation of secondary alcohols –>
Ketone
Oxidation of tertiary alcohol
No reaction
How to collect aldehyde in oxidation of primary alcohol
Distillation
How to produce carboxylic acid from oxidation of primary alcohols
reflux
Electrophilic substitution with benzene (chlorine)
Cl+ → chlorobenzene
Electrophilic substitution with benzene (NO2)
NO2+ → nitrobenzene
Esterification
Alcohol + carboxylic acid → ester + H2O
