Thanks does this rule applies for all namings of such things
plz if u  can help me with the rules of naming organic structures post anythigappreciating any effort

see this

http://www.khanacademy.org/v/naming-alkanes-with-alkyl-groups?p=Organic%20Chemistry

and some few video of example see the list of videos at

http://www.khanacademy.org/#organic-chemistry

are very helpful

because cl2 is diatomic so u would have a combination of 1-35+35=70   2-35+37=72   3-37+37=74
and for D it equals 35+37 for the cl2+ ion hope u understood

if You have got data booklet see in it

[EMO123]

q # 14

isomers are representation of molecular formula in different structural form
