Preparation and Properties of Alcohols starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Preparation and Properties of Alcohols. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 12

Calculate the number of moles of ethanol present in 46 g of ethanol (molar mass = 46 g/mol).

Describe the mechanism of nucleophilic substitution in the preparation of alcohols from alkyl halides.

Describe the process of fermentation for the preparation of ethanol.

Explain the difference between primary, secondary, and tertiary alcohols with examples.

Explain why alcohols are soluble in water.

Explain why tertiary alcohols react faster with Lucas reagent than primary alcohols.

Explain why the boiling point of ethanol is higher than that of dimethyl ether, although both have the same molecular formula.

Name the type of alcohol formed when propene reacts with water in the presence of acid as a catalyst.

State the product formed when ethanol is oxidized with acidified potassium dichromate.

What is the major product when 2-methyl-2-propanol is dehydrated?

What is the product when phenol reacts with bromine water?

Which alcohol is commonly known as wood alcohol?

Which alcohol is used as an antiseptic in medical wipes and hand sanitizers?

Write the balanced chemical equation for the reaction of sodium with ethanol.

Write the equation for the preparation of ethanol from ethene.

A student adds excess sodium metal to an unknown alcohol and observes rapid effervescence. Which property of alcohols does this test demonstrate, and what gas is evolved?

Arrange the following alcohols in increasing order of acidity: methanol, ethanol, 2-propanol, tert-butanol. Justify your answer based on structure and inductive effects.

Calculate the mass of ethanol (C₂H₅OH) required to produce 4.48 L of hydrogen gas at STP by reaction with sodium metal. (Molar mass of ethanol = 46 g/mol; 1 mol gas at STP = 22.4 L)
