when is an alkene an E isomer
when the two high priority groups attached are on the same side of the carbon double bond
ethene reacts with chlorine to produce?
give the structural formula
ClH2CH2Cl
what family is formed when ethene reacts with aqueous potassium manganate
alcohol
state why the empirical formula of a poly(alkane) is the same as that of the monomer from which it is produced
they have the same C:H ratio in their simplest forms
what the atom economy for the production of a poly(alkene) from an alkene and why?
100% because there are no waste products formed in addition polymerisation
what are three problems as a result of incomplete combustion
-production of carbon monoxide which is poisonous/toxic gas
-unburned hydrocarbons react together to form compounds which are toxic
-Carbon particulate are released into the atmosphere
main problem from complete combustion of alkane fuels
carbon dioxide is a greenhouse gas, that traps heat from the earth, reradiating it to the earth and damage the ozone
what does a single headed curly arrow mean
denotes 1 electron pair is moving
what does a double headed curly arrow mean
denotes a lone electron pair
suggest why a small amount of UV light can result in the formation of a large amount of product (use chlorine)
chlorine radical is regenerated by the propagation each time a molecule of product is formed
scientists never detect molecular hydrogen H2 amongst the products of the chlorination of methane
suggest why?
UV light does not have enough energy to break C-H bonds
so no H free radicals, therefore they could not combine to make H2
