ch 7- families of organic compounds Flashcards
addition reaction
a reaction in which one molecule combines with another molecule to form a larger molecule
alkane
hydrocarbon that contains only single carbon to carbon bonds
alkene
hydrocarbon with at least one double carbon to carbon bond
alkyne
hydrocarbon with at least one triple carbon to carbon bond
carbon chain
linear set of carbon atoms in a hydrocarbon
homologous series
series of hydrocarbons with a similar chemical structure and chemical properties
hydrocarbon
compound consisting of hydrogen and carbon only
organic compounds
compounds consisting of carbon atoms most commonly covalently bonded to H, N, P or O atoms
saturated hydrocarbon
a hydrocarbon possessing only single bonds bewteen carbon atoms
substitution reaction
one atom or group of atoms replacing a part of another molecule
unsaturated hydrocarbon
a hydrocarbon possessing at least one double bond between atoms
organic
when a molecule is an organic molecule, it is carbon based and may be either naturally or synthetically produced
homologous series are similar as:
they have similar physical and chemical properties
a similar structure
the same general formula
alkane: general formula
CnH2n+2
alkene: general formula
CnH2n
alkyne: general formula
CnH2n-2
alkanes: structure
chain like sequence of carbons with single bonds only- saturated
alkanes: uses
fuels
cooking oils
solvents for chemical manufacturing processes
alkanes: physical properties BLIC
boiling/melting point depends on chain length (more carbons, harder it is to break)
less dense than water
insoluble in water
colourless
alkanes: chemical properties
RUC
relatively unreactive
can undergo substitution reactions under UV light
combustible
alkenes: structure
chain like sequence of carbons with one or more double bonds- unsaturated
alkenes: use
precursors in many chemical manufacturing processesp
alkenes: physical properties
similar to alkanes but can differ depending on the amount of double bonds present:
boiling/melting point depends on chain length (more carbons, harder it is to break)
less dense than water
colourless
insoluble in water
alkenes: chemical property- RIA
reactive
incomplete combustion
addition reactions readily
alkane vs alkene boiling point
alkanes>alkenes
Since alkene molecules have two less electrons than an alkane of the same number of carbons, its dispersion force is slightly weaker.
alkyl group
a side chain attached to the parent carbon chain, containing only carbon and hydrogen atoms
nomenclature
system developed in order to identify organic compounds
parent chain
longest continuous chain of carbon-carbon bonds
parent name
component of systematic name that refers to the length of the parent chain
structural isomers
isomers that have the same molecular formula but the atoms are arranged in a different spatial arrangement
naming convention of simple saturated hydrocarbons
indicate the number of carbons in the parent chain (e.g. prop-)
indicates the type of bondingbetween the carbons in the carbon chain (e.g. -ane)
e.g. propane

prop-
carbon chain length: 4
but-

dec-
naming convention of unsaturated hydrocarbons
number of carbons in the parent chain (pent-)
position of the carbon to carbon double/triple bond (-2-)
types of bonding between carbons in the parent chain (-ene)
e.g. pent-2-ene
