NaBH4

Generally, molecules are coloured as they absorb visible frequencies of light, to promote an electron to a higher energy level, so the other (complementary) frequencies of light pass through the sample an...

Type of reaction: nucleophilic addition to carbonyl

Diagram should show nucleophilic attack of oxygen of alcohol on carbon of carbonyl in the acyl chloride. Lone pair clearly shown on the oxygen, f...

Nucleophilic substitution using NaOH to convert haloalkane to primary alcohol. This is a mechanism that you need to know for the exam. Then oxidise the alcohol by refluxing with acidified potassium dichro...

An acid when dissolved in a liquid, will produce hydrogen ions (H+) while a base will produce hydroxide ions (OH-). When a litmus paper is used to test acids and bases, acids turn the litmus paper red whi...
