🌏NOTES 🌺OXIDATION OF ALCOHOL Basic knowledge: Alcohol can be divided into three classes 🤔 which are, 🍁Primary (1°) alcohol 🍁Secondary (2°) alcohol 🍁Tertiary (3°) alcohol And how them can be classified❓❓ They classified based on carbon that "OH" group attached, if "OH" group attached to 🌿 1° carbon --> 1° alcohol 🌿 2° carbon --> 2° alcohol 🌿 3° carbon --> 3° alcohol ----------------- 🍄Oxidation of 1° alcohol 1° alcohol can be oxidized into 2 organic compounds: 🌳Aldehyde 🌳Carboxylic acid If 1° alcohol oxidized by using MILD (weak) Oxidizing agent, therefore.. 1° alcohol ---> Aldehyde But if using STRONG Oxidizing agent🤔, therefore.. 1° alcohol ---> Carboxylic acid ------------------- 🍄Oxidation of 2° alcohol 2° alcohol can be oxidized into ketone ONLY🤓 2° alcohol ---> Ketone ------------------- How about 3° alcohol ❓😎 3° alcohol --> ❓

Hi , how was your chemistry preparation for pspm II / IV 2023 ?

(ii) What is product when compound E reacts with dilute, alkaline potassium permanganate solution ? 🤔

Compound E gives only propanone when reacts with hot and acidified potassium permanganate solution. (a) Name the compound E

Name the following compounds according to IUPAC nomenclature ☺️

1) The oxidation of 2-propanol (2° alcohol) using acidified KMnO4 solution yields ketone A. 2) when carbonyl compounds react with Grignard reagent, the alkyl group from the Grignard reagent is added to carbonyl carbon atom of carbonyl compounds. Alcohol is formed after hydrolysis
