Front (Question)

Observation is Aldehyde present & Oxidised w/ Tollens’ Reagent?

Back (Answer)

Ag⁺ + e⁻ |> Ag(s) Silver Mirror

Front (Question)

Oxidation product of Secondary Alcohols?

Back (Answer)

Ketone

Front (Question)

What can the Organic tests be used to Confirm?

Back (Answer)

Presence & Identity of Organic Impurities

Front (Question)

Oxidation product of Primary Alcohols?

Back (Answer)

Aldehyde Carboxylic Acid

Front (Question)

Organic product when a Carboxylic Acid reacts with Na₂CO₃?

Back (Answer)

Carboxylate Salt e.g. Sodium Ethanoate

Front (Question)

Will Ketones React with either Tollens’ Reagent or Fehling’s solution?

Back (Answer)

No - Ketones cannot be oxidised

Front (Question)

Oxidising Agent in Oxidation of Alcohols?

Back (Answer)

Acidified Potassium Dichromate H⁺/Cr₂O₇²⁻

Front (Question)

General Equation of Oxidation of Aldehyde?

Back (Answer)

R-C(=O)-H + [O] |> R-C(=O)-OH

Front (Question)

Test for Presence of Aldehydes?

Back (Answer)

Mild Oxidising Agents: e. g. Tollens’ Reagent e. g. Fehling’s solution

#10

Front (Question)

Observation when Carboxylic Acid reacts with Na₂CO₃?

Back (Answer)

Fizz CO₂ produced

#11

Front (Question)

General Equation of Oxidation of Secondary Alcohols?

Back (Answer)

R-C-(H,OH)-R + [O] |> R-C(=O)-R + H₂O

#12

Front (Question)

Can Ketones be Oxidised further?

Back (Answer)

#13

Front (Question)

Why is the Product of Oxidation of a Primary Alcohol most likely to be an Aldehyde when formed through Immediate Distillation?

Back (Answer)

Aldehyde has Lower Boiling Point than Alcohol (pd-pd weaker than H-bond) Turns into a gas & cannot react further

#14

Front (Question)

Observations for Oxidation of Secondary Alcohols

Back (Answer)

Orange |> Green

#15

Front (Question)

In Organic Chemistry, what is Oxidation?

Back (Answer)

Creation of more C-O bonds

#16

Front (Question)

General Equation for Oxidation of a Primary Alcohol to a Carboxylic Acid?

Back (Answer)

R-CH₂-OH + 2[O] |> R-C(=O)-OH + H₂O

#17

Front (Question)

How can H⁺/Cr₂O₇²⁻ be used to identify Tertiary Alcohols?

Back (Answer)

No Observable Change

#18

Front (Question)

Observations for Oxidation of a Primary Alcohol to an Aldehyde?

Back (Answer)

Orange |> Green

#19

Front (Question)

How is Fehling’s solution formed?

Back (Answer)

Add Fehling’s 1 to Fehling’s 2 Copper Sulfate to Potassium Sodium Tartrate

#20

Front (Question)

Organic product when Aldehyde present & Oxidised with Fehling’s solution?

Back (Answer)
