In question number 9 ,all the options seem to be right but option c is said to be wrong in the answer
I am not able to understand why this is so

Here the longest chain is pentane and chloro and methyl are the substituents   

No the longest chain seems to be hexane to me in option number 4

I answered for c option that why it is wrong
option 4 is d ...that is correct nomenclature......nothing wrong in that name

hi 
you are talking about nomenclature. i m not sure please search about this at google.

Option C in the image attached above is wrong
Check correct answer
