Carbon and its Compounds | Activities in Text Book with Solution

Activity 4.3

CAUTION: This Activity needs the teacher’s assistance.

Take some carbon compounds (naphthalene, camphor, alcohol) one by one on a spatula and burn
them.

Observe the nature of the flame and note whether smoke is produced.

✅ Answer:

  • Camphor & Naphthalene are unsaturated hydrocarbons. So they burn with yellow flame and leave residues.
  • Alcohol is saturated and burns with clean blue flame.
Place a metal plate above the flame. Is there a deposition on the plate in case of any of the compounds?

✅ Answer: There is deposition in the case of naphthalene and camphor on the plate.
