Predict the products and reactants of the reaction and classify the type of reaction?

Question

Pent-1-ene is produced from pentan-1-ol

type of reaction: (addition, substitution, elimination?)

Answer 1

CH₃CH₂CH₂CH₂CH₂OH → CH₃CH₂CH₂CH=CH₂ + H₂O

Pentan-1-ol H₂SO₄ Pent-1-ene

Because the elements of water have been removed from the pentanol molecule, the reaction type is a special form of elimination known as dehydration, and is usually carried out in the presence of concentrated sulfuric acid.
