What are the hazards of dichloromethane?
Methylene chloride (CH2Cl2) is a colorless liquid that can harm the eyes, skin, liver, and heart. Exposure can cause drowsiness, dizziness, numbness and tingling limbs, and nausea. It may cause cancer. Severe exposure can cause loss of consciousness and death.
What is ch2c12?

What functional group is dichloromethane?
(i) The functional group in CH2Cl2 is chlorine. (ii) CH2Cl2 has one carbon atom and has to be named as the derivative of methane. (iii) CH2Cl2 contains 2 chlorine atoms, therefore the prefix dichloro- is to be added to the parent alkane, methane. (iv)Therefore, IUPAC name is dichloromethane.
