Physics. 2 Edition. Short Answer. Step-by-step Solution. Key Concepts. Chapter 32: Problem 69. A layer of methyl alcohol, with index of refraction 1.329, rests on a block of ice, with index of refraction 1.310. A ray of light passes through the methyl alcohol at an angle of φ 1 = 61.07 ∘ relative to the alcohol-ice boundary.
23 Ιουν 2023 · The general formula for an alcohol may be written as R—OH, where R represents the hydrocarbon (alkane) portion of the molecule and is called an alkyl group. In methanol, R is the methyl group CH 3 .
2 ημέρες πριν · CH3OH is the molecular formula of methanol, also known as methyl alcohol, which is the simplest aliphatic alcohol. It is primary alkyl alcohol in which a methyl group is linked to a hydroxyl functional group. It is a polar solvent due to the presence of a hydroxyl functional group.
Methanol, also known as methyl alcohol or wood alcohol, is a chemical compound with the formula CH3OH. It is the simplest alcohol, consisting of a methyl group (CH3) bonded to a hydroxyl group (OH). Methanol is a colourless, volatile liquid that is highly flammable. It has a distinctive odour and is miscible in water.
explain why the boiling points of alcohols and phenols are much higher than those of alkanes, ethers, etc., of similar molecular mass. discuss the factors that are believed to determine the acidity of alcohols and phenols.
Alcohols contain an -OH group and follow the general formula CnH 2n+1OH. They can be produced via two main methods. Hydration. This method produces alcohols from alkenes in the presence of an acid catalyst. Phosphoric acid is commonly used as the catalyst under aqueous conditions at 300oC and high pressures. Example:
Methanol is simplest alcohol with chemical formula CH 3 OH. It is not a hydrocarbon since the hydroxyl group is chemically bonded to the carbon atom. It consists of a methyl group linked with a hydroxyl group. It is also known as Wood alcohol or Methyl alcohol.
