Answer 2

Answer: D. Naphthalene

Explanation:

Naphthalene is a colorless, crystalline, solid aromatic hydrocarbon with a pungent odor. It melts at 80°C, boils at 218°C, and sublimes upon heating. It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and really soluble in ether, chloroform, or compound . Naphthalene is obtained from coal tar, a remains of the coking of coal. It is used in mothballs and gives them their characteristic odor. From it are prepared derivatives that are utilized in the preparation of dyes and as insecticides and organic solvents. The molecular structure of naphthalene is that of two benzene rings fused along side two adjacent carbon atoms common to both rings.
