Acid Chloride are the derivatives of carboxylic acids which have –COCl group in it.
Rules:
1.Start numbering from the carbon of –COCl.
2.For naming: alkane-e+ oyl chloride
In the above compound, five carbon is present.
Thus the name of the compound is- pentane-e + oyl chloride
3.If two -COCl group is present, always keep the -COCl on the two terminals irrespective of the length of the chain.
4.It is named as: Alkanedioyl dichloride
5.If three -COCl is present, the stem chain holding the -COCl group directly is considered as the parental chain.
6. It is named as : Alkane-x,y,z-tricarbonyl trichloride
7.If three -COCl is present but of it is not directly attached to the stem chain. Then the longest chain holding two -COCl in the terminals are chosen as the parental chain. and the 3rd -COCl is named as : chloro oxo alky
