draw and name it.
I can identify the position of the function group of a molecule by
numbering carbons appropriately.
I can name and draw primary, secondary, tertiary and
quaternary molecules and explain why they are defined as such.

I can show understanding of substitution, elimination and
addition reactions by defining each and describing which
molecules undergo these types of reactions.
I can show understanding of oxidation and reduction reactions
by defining each (in terms of electrons, hydrogen and oxygen)
and describing which molecules undergo these reactions.
I can state Markovnikov’s rule and Saytzeff’s rule.
I can show that I understand Markovnikov’s rule and Saytzeff’s
rule by drawing and labelling the major and minor products of
unsymmetrical addition and elimination reactions.
APPLYING KNOWLEDGE OF ORGANIC REACTIONS:
I can show understanding of the reactivity of molecules by
identifying acidic, basic and neutral molecules and explaining
how to identify these molecules using moist red or blue litmus
paper.
I can show understanding of the differences between aldehydes
and ketones by explaining how to distinguish between them
using Tollens, Benedicts or Fehlings reagents and describing any
observations that would occur.
I can show understanding of how acyl chlorides differ from other
molecules by discussing why they are so reactive and
observations that may occur when they react.

I can show understanding of organic reactions by confidently
being able to describe how to use a range of reagents to
distinguish between given substances based on observations
including colour, separation, bubbles, reactivity, smell etc.
I can show my ability to link my understanding of different
organic reactions by filling in products, reactants, reagents and
conditions to complete any given reaction scheme.
I can show my ability to link my understanding of different
organic reactions by drawing my own reaction scheme to show
what steps would be necessary to form any molecule from any
other molecule (of the molecules covered).
ISOMERS:
I can define ‘structural isomers’ concisely, in terms of molecular
and structural formulas.
I can show that I understand structural isomers by naming and
drawing all possible structural isomers of a given molecule, if
given the structural or molecular formula.
I can show further understanding of structural isomers by
including structural isomers that do not necessarily have the
same functional group or carbon chain length as the given
molecule.
I can explain what geometric isomers are in terms of the inability
of a double bond to rotate.
I can show that I understand geometric isomers by drawing and
naming geometric isomers and identifying them as cis or trans.
I can explain what optical isomers are in terms of chiral carbons
and the inability to be superimposed.
I can show that I understand optical isomers by identifying a
chiral carbon in a given molecule and drawing its optical isomer.

I can state how to distinguish between optical isomers in terms
of plane polarised light.
POLYMERS:
I can show that I understand addition polymerisation by drawing
a polymer made up of a given monomer or drawing the
monomers that make up a given polymer.
I can show that I understand condensation polymerisation by
identifying the monomers required to form a polyamide or a
polyester.
I can explain the importance of each monomer having a
functional group on both ends (i.e. dialcohol, dicarboxylic acid,
diamine, diacyl chloride).
I can show that I understand why these particular monomers are
required by identifying ester and peptide linkages and explaining
how they arise from the monomers.
I can show that I understand the significance of ester and peptide
linkages by identifying the products of the hydrolysis of
polyesters and polyamides (under both acidic and basic
conditions).
I can apply my understanding of polymerisation to natural
polymers including:
The reaction of amino acids to form polypeptides.
The reaction of glycerol and fatty acids to form fats
(triglycerides).
The reaction of fats and bases to form soap
(saponification).

PHYSICAL PROPERTIES:
I can show that I understand the significance of the structure
of each functional group by explaining the relative solubility of
each functional group in terms of polarity and hydrogen
bonding.
I can show that I understand the significance of the structure of
each functional group by explaining the relative melting and
boiling points of each functional group in terms of polarity and
hydrogen bonding.
I can show that I understand that assumptions about the above
physical properties of two molecules can only be made if they
are comparable (same carbon chain length) by explaining the
effect of greater mass (more electrons) on these physical
properties.
I can show that I understand the importance of molecular
structure by identifying whether a straight-chain or a
branched-chain structural isomer is likely to have a higher
melting and boiling point.
I can show that I understand the importance of molecular
structure by identifying whether a cis or trans geometric isomer
is likely to have a higher melting and boiling point.
