1.	Which of the following is incorrect with regard to the reaction between C2H4 and Cl2 in CCl4?(a) It results in the formation of a vicinal dihalide(b) It results in the breaking of the C-C double bond(c) It results in the formation of a colourless compound(d) It results in the discharge of a reddish-brown colourThe question was asked in a job interview.Question is from Methods of Preparation of Haloalkanes in chapter Haloalkanes and Haloarenes of Chemistry – Class 12
Answer» The CORRECT option is (d) It results in the discharge of a reddish-brown colour To elaborate: The reddish-brown colour is discharged when Br2 reacts with an alkene to form a vic-dihalide. This makes it an IMPORTANT test for the detection of a double BOND.
