Alcohols common mistakes

Common mistakes

• Confusing fermentation with hydration

  Students often confuse the processes of fermentation and hydration, thinking they are the same.

  Fix itRemember that fermentation is a biological process using yeast, while hydration is a chemical reaction involving ethene and water.

• Incorrect balancing of equations

  Failing to balance the number of atoms of each element on both sides of the equation.

  Fix itAlways check that the number of atoms for each element is equal on both sides of the equation before finalizing.

• Confusing primary and secondary alcohol oxidation products

  Stating that primary alcohols are oxidized to ketones.

  Fix itPrimary alcohols are oxidized to aldehydes, not ketones.

• Confusing E1 and E2 mechanisms

  Students often mix up the steps involved in E1 and E2 mechanisms.

  Fix itRemember that E1 involves a carbocation intermediate, while E2 is a concerted reaction.

• Confusing primary and secondary alcohols

  Students often misidentify primary alcohols as secondary due to the structure of the carbon chain.

  Fix itCarefully analyze the carbon atom to which the -OH group is attached and count the number of carbon atoms it is bonded to.
