These flashcards explain how transition metal compounds dissolve in water to form metal-aqua complex ions, how water molecules coordinate with metal ions, and why such solutions are acidic due to hydrolysis releasing H⁺ ions.

What are structural isomers?

Have same molecular formula but different structural formulas

Name 3 types of structural isomers

  • Chain Isomers

  • Positional Isomers

  • Functional Group Isomers

What is a chain isomer?

  • Same molecular formula

  • Hydrocarbon chain is arranged differently

What is a positional isomer?

  • Compounds with same molecular formula

  • But different structures due to different positions of the same functional group on

What are functional group isomers?

  • Same molecular formula

  • Have the same atoms but have different functional groups

_____ show E/Z Isomerism

Alkenes

The atoms connected to the C=C double bonds _ rotate around them like they can around single bonds

Cannot

What causes the type of stereoisomerism called E/Z isomerism?

Restricted rotation around the (planar) C=C double bond

Explain how alkenes show E/Z isomerism

  1. Alkenes have restricted rotation around their C=C double bonds

  2. & if both of the double-bond carbons have different functional groups attached to them = get 2 stereoisomers (E/Z isomerism)

Where are the same groups situated in (cis) Z-isomer?

Either both above or both below double bond

(matching groups are on 'ze zame zide')

Where are the same groups situated in (trans) E-isomer?

What rules do we use to identify whether a molcule with a C=C bond, surrounded by 3 or 4 different functional groups, is a E- or Z- isomer?

Use the Cahn-Ingold-Prelog (CIP) priority rules

Describe how we use the CIP rules to identify a E-/Z-isomer

  1. Identify the groups directly bonded to each of the C=C carbon atoms

  2. Assign a priority by finding the atom with the highest atomic number - this given the highest priority

  3. If higher priority groups = same side of molecule = Z-isomer OR if higher priority groups = different sides of molecule = E-isomer

CIP rules: What do you do if the atoms directly bonded to carbon are the same?

Look at next atom in the groups to work out which has the higher priority

Why is the IUPAC system used for naming organic compounds?

It's the agreed international language of chemistry so it allows scientific ideas to be communicated across the globe more effectively

What are mechanisms?

Diagrams that break reactions down into individual stages

What reaction do mechanisms show?

How molecules react together

What do curly arrows show?

How electron pairs move around in reactions

As electrons are _____, they move from areas of high _ _____ to more _ ____ areas

As electrons are negatively charged = move from areas of high electron density to more positively charged areas

(e.g. pair of electrons = attracted to carbon atom at positive end of a polar bond)

Explain how free radicals form?

  1. Sometimes a covalent bond may break in such a way that 1 electron goes to each atom that originally formed the bond

  2. These fragments of original molecule have an unpaired electron = called free radicals

Free radicals are extremely ____

reactive

How are free radicals represented?

By a dot

| (e.g. CH3• = methyl radical)

What is the functional group of an ester?

-COO

State the name of CH3CH=CHCH2OH

But-2-en-1-ol
