1. While writing the IUPAC name, write the name of side substituent according to the alphabetical order. That is why bromo is written before chloro as B comes before C.

2. Always use a hyphen {-} between a number and a alphabet. Since Br is attached to 1 position and Cl isattached to fourthposition i.e. it is written as 1-Bromo and 4-chloro.

3. Also there is a presence of triple bond at the second carbon so the suffix used for triple bond is “yne” along with the position of the bond i.e. but-2-yne )
