WebIn Part-II, you will get to know about the phenols, their preparation, properties and uses. These CBSE revision notes are based on the latest CBSE syllabus for CBSE Class 12th Chemistry. The main topics covered in this part are: o Phenols • Classification • Nomenclature • Preparation • Physical properties • Chemical properties WebAlcohol = R-OH Phenol = Ar-OH. Ethers have two alkyl or aryl groups attached to an oxygen atom. The general structure of an ether is R-O-R', where R' again is any alkyl group. ... In an alcohol molecule, the hydroxyl oxygen and the two atoms bonded to it are all in the same plane and have a bond angle of approximately 104 o. This is very ...

WebJul 1, 2024 · Boiling Points of Alcohols. The oxygen in alcohols and phenols is sp 3 hybridized which gives the roughly the same tetrahedral geometry as water. The bond angle of methanol (108.5 o) is slightly less than the tetrahedral value mainly due to the presence of its lone pair electrons.. The presence of a highly electronegative oxygen confers a … WebIn alcohols, two lone pair of electrons are present. Therefore, there is comparatively more repulsion and less bond angle. The C - O - C bond angle (111.7 ∘) in ether is slightly greater than the tetrahedral angle due to the repulsive interaction between the two bulky (- … northern tool sand lake
