Molecule names: 1 = 1-bromobut-1-ene (seen as either E-1-bromobut-1-ene or Z-1-bromobut-1-ene) 2 = 2-bromobut-1-ene 3 = 3-bromobut-1-ene 4 = 4-bromobut-1-ene 5 = 1-bromobut-2-ene (seen as either E-1-bromobut-2-ene or Z-1-bromobut-1-ene) 6 = 2-bromobut-2-ene (seen as either E-2-bromobut-2-ene or Z-2-bromobut-2-ene) 7 = 1-bromo-2-methylprop-1-ene 8 = 3-bromo-2-methylprop-1-ene 9 = bromocyclobutane 10 = 1-bromo-2-methylcyclopropane 11 = 1-bromo-1-methylcyclopropane 12 = bromomethylcyclopropane (not expected at A-level) Definitions: Structural isomerism = molecules with the same molecular formula but different structural formula. Stereoisomerism = molecules with the same structural formula but the atoms are arrange different in the space provided Essential Criteria for E/Z isomerism = each carbon in the C=C must be bonded to at least 2 different atoms or groups. Essential criteria for cis/trans isomerism = each carbon in the C=C must be bonded to at least 2 different atoms or groups and each carbon must also be bonded to an example of the same substituent group. (please also note that cis/trans is not only limited to the hydrogen atoms in the C=C) OCR clarified their stance on E/Z and cis/trans criteria here = https://ocr.org.uk/news/content-clari... Chiral centre (aka chiral carbon) = a carbon atom bonded to at least 4 different atoms or groups.
