| CH3.CO.OH is called | ethanoic acid |
| H.CO.OH is called | methanoic acid |
| CH3.CH2.CO.OH is called | propanoic acid |
| the OH bond is more strongly polarised in CH3.CO.OH than in C2H5OH | because of the strongly electron attracting C=O group |
| CH3.CO.OH + H2O forms | CH3.CO.O(-)aq + H (+)aq |
| CH3.CO.OH is a weaker acid than HCl because | only partially dissociated into its ions |
| HCl is a strong acid because | it is completely dissociated into its ions |
| CH3.CO.OH is a weak acid so its conjugate base | CH3COO(-) is strong |
| CH3.CO.OH + NaOH forms | CH3.CO.O(-) Na(+) & H2O |
| CH3.CO.OH + NaHCO3 forms | CH3.CO.O(-) Na(+) & H2O & CO2 |
| CH3.CO.OH + NaHCO3 observation | effervescence (as CO2 liberated) |
| CH3.CO.OH + PCl5 observation | white acidic fumes (HCl) |
| CH3.CO.OH + PCl5 forms | CH3.CO.Cl + HCl + POCl3 |
| CH3.CO.Cl is called | ethanoyl chloride |
| CH3.CO.OH + CH3.CH2OH + conc H2SO4 or HCl observation | sweet smelling product |
| CH3.CO.OH + CH3.CH2OH + conc H2SO4 or HCl formula? | CH3.CO.O.CH2.CH3 + H2O |
| CH3.CO.O.CH2.CH3 name is .. | ethyl ethanoate |
| CH3.CO.O.CH2.CH3 type of compound | ester |
| CH3.CO.Cl + CH3.CH2OH gives better yield because | it's not reversible |
| H.CO.OH + CH3.CH2OH formula of product | H.CO.O.CH2.CH3 + H2O |
| CH3.CO.OH + LiAlH4 organic formula of product is | CH3.CH2.OH |
| LiAlH4 acts as a | reducing agent |
| LiAlH4 conditions needed | dry ether |
| CH3.CO.OH + CH3.CH2OH needs conc H2SO4 or HCl | H2SO4 or HCl catalyse the reaction |
| CH3.CO.OH + CH3.CH2OH forms equilibrium H(+) affect on yield | none |
| CH3.CO.OH + CH3.CH2OH forms equilibrium H(+) | increases rate equilibrium established |
| CH3.CH2OH forms CH3COOH reagents | sodium dichromate in acid solution |
| CH3.CH2OH forms CH3COOH conditions needed | heat under reflux |
| CH3.CH2OH forms CH3COOH heat under reflux to | prevent loss of products or reactants by evaporation |
| CH3.CH2OH forms CH3COOH to reduce risk of fire | heat under reflux |
| When heating under reflux a condenser is placed in a | vertical position |
| Heat change when NaOH neutralises one mole of CH3COOH | is less exothermic than for 1 mole HCl |
| Enthalpy of neutralisation of CH3COOH less than HCl because | some of the heat needed to break O-H that have not already broken |
