C6.2 Organic chemistry

Summary Carbon chemistry is the basis of life on Earth. Organic chemistry is the basis of many of the materials we produce. Organic compounds are covalent in nature and react in a predictable pattern. Crude oil forms the basis of many useful by-products. Underlying knowledge and understanding Learners should be familiar with reactions and displayed formula. Common misconceptions Learners tend not to bring the concepts from general chemistry in their study of organic chemistry. They have difficulty identifying functional groups and naming and drawing the compounds.

Learning outcomes	To include	Maths	Working scientifically

$C6.2a ☑ recognise functional groups and identify members of the same homologous series$	$homologous series, of alkanes, alkenes, alcohols and carboxylic acids$
$C6.2b ☑ name and draw the structural formulae, using fully displayed formulae, of the first four members of the straight chain alkanes, alkenes, alcohols and carboxylic acids$		$M5b$	$WS1.4a$	$Use of models.$
$C6.2c ☑ predict the formulae and structures of products of reactions of the first four and other given members of the homologous series of alkanes, alkenes and alcohols$	$combustion; addition of bromine and hydrogen across a double bond; oxidation of alcohols to carboxylic acids using potassium manganate(VII)$
$C6.2d ☑ recall the basic principles of addition polymerisation by reference to the functional group in the monomer and the repeating units in the polymer$
$C6.2g ☑ deduce the structure of an addition polymer from a simple alkene monomer and vice versa$	$the following representation of a polymer [repeat unit]ₙ$		$WS1.4a$
$C6.2h ☑ recall that DNA is a polymer made from four different monomers called nucleotides and that other important naturally-occurring polymers are based on sugars and amino-acids$	$the names of the nucleotides$		$WS1.4a$
$C6.2i ☑ recall that it is the generality of reactions of functional groups that determine the reactions of organic compounds$			$WS1.4a$
