(i) Give the name of the carbon-containing product formed when the alcohol in Figure 15 undergoes
dehydration.

Answer 1

The carbon-containing product formed when the alcohol in Figure 15 undergoes dehydration is an alkene and water.

The carbon-containing product formed when the alcohol in Figure 15 undergoes dehydration is an alkene and water.

Dehydration of an alcohol involves the removal of the OH group from the alcohol carbon atom and a hydrogen atom from an adjacent carbon atom in the same molecule.

In this case, the OH group is removed from the OH-bearing carbon atom (ĊĊĊOH), and a hydrogen atom is removed from one of the carbon atoms adjacent to it.
