6i don think it exists..........

Ans: Methylcyclobutane and 1,2-Dimethylcyclopropane.
Why not 1,1 - dimethylcyclopropane?

1As far as I think, I find no reason to rule out 1,1 Dimethylcyclopropane.
And also why can't we have Ethylcyclopropane?
And Akhil, we don't check their existence while checking the possible isomers. Could you please elaborate your pt :)
Thanks
11,1-dimethylcyclopropane should be there. I see no reason to exclude it.
1Maybe akhil wants to say tat1,1-Dimethylcyclopropane is too strained to exist.
But agreed to vishuboy.you dont need count their existence to check the isomerism.
And 1-methylcyclobutane may also be one isomer.
I think answer is 1-methyl cyclobutane and 1,2-dimetyl cyclopropane shud be the answer.
I will go with the strained theory i gave.
1i think u can write either 1,1 - dimethylcyclopropane or 1,2-Dimethylcyclopropane as its chain isomers cuz these are positional isomers of each other and not chain isomers!!!!!!!
or u can make pairs like
cyclopentane ; 1,1 - dimethylcyclopropane are chain isomers
cyclopentane ; 1,2 - dimethylcyclopropane are chain isomers
cyclopentane ; Methylcyclobutane are chain isomers
bt
1,1 - dimethylcyclopropane ; 1,2 - dimethylcyclopropane show positional isomerism!!!
