Value of n and m

You got it completely, Madhu?

Look at this. You'll understand.

Just go through all my comments once, you'll get the whole concept. Fractional distillation doesn't differentiate between optical and geometrical isomers.

please ask if you don't get anything

Hope you understand this

See this

sir., i have asked you some doubt! yesterday hope you didn't receive! can i make sure that you'll clear it today?

Dear Madhu, I didn't receive anything. You can ask today, no worries.

here 6 isomers obtained out of which 4 can be separated

when the monochlorination reaction proceed by the 2 methyl butane , we get 4 isomers (ignoring optical isomers ) in form of the product . isomers have identical chemical formula but their structure are different each other.

enantiomers can't be separated by any physical method

got it??

so is there no need of making decisions with respect to stability? because in accordance with stability. only one product is possible!

no no

also kindly explain me the other 2 isometric products sir

here i and ii are enantiomers so their mirror image can't be separated. and iii, iv are optically inactive so these can be separated

so total 4 forms can be separated by frictional distillation

diastereoisomers have different physical properties so they can be separated but enantiomers can't be separated

got it?

please accept the answer if you got it 🙏🙏

Have a look.

sir in second structure..the carbon which is attached to Cl isn't a chiral carbon. but you have taken the other carbon (chiral)which is next to it why so?
