Question
What are polyhalogen compounds? Write note on dichloromethane (Methylene Chloride)

Answer

→ "Carbon compounds containing more than one halogen atom are usually referred to as polyhalogen compounds."
CH2 CI2:
→ Dichloromethane is widely used as a solvent as a paint remover, as a propellant in aerosols, and as a process solvent in the manufacture of drugs.
→ It is also used as a metal cleaning and finishing solvent.
→ Methylene chloride harms the human central nervous system.
→ Exposure to lower levels of methylene chloride in air can lead to slightly impaired hearing and vision.
→ Higher levels of methylene chloride in air cause dizziness, nausea, tingling and numbness in the fingers and toes.
→ In humans, direct skin contact with methylene chloride causes intense burning and mild redness of the skin.
→Direct contact with the eyes can burn the cornea.
