Answer 1

Answer:

Naphthalene burns with yellow flame and and alcohol burns with blue flame.

Explanation:

Naphthalene will give a yellow sooty flame because they are unsaturated. Unsaturated compounds generally give yellow sooty flame.

Alcohol burns with blue flame. Its probably because the container stops air from being sucked freely into the base of flame. Usually, it contains ethanol and methanol which burns with a pure blue flame as well.
