The given passage provides information about the organic compound A and its reactions to form compounds B and C. From the given information, we can deduce the general formula for alkene.
Key points:
- Compound A has a molecular formula of C2H4.
- On reduction, compound A forms compound B with a molecular formula of C2H6.
- Compound B reacts with chlorine in the presence of sunlight to form compound C with a molecular formula of C2H5Cl.
Analysis:
- The reduction of compound A to form compound B suggests the addition of hydrogen atoms to compound A.
- The reaction of compound B with chlorine in the presence of sunlight suggests the substitution of a hydrogen atom with a chlorine atom.
Answer:
The general formula for alkene is CnH2n. In this case, the compound A has a molecular formula of C2H4, which corresponds to an alkene.
