I've made this mistake so I wanted to clarify for those looking--adding an ethyl group tends to change the chain. For instance hexane. Adding an ethyl group to the a 3-carbon chain just creates a 4-carbon chain with two methyl groups. It looks different at first glance, but you always want to make sure to recount the longest chain. That being said, for heptane there are nine structural isomers.

in 4:16 should it be named 2,2-dimethylpropane?

He did say "2,2-dimethylpropane" but miswrote the name as ~pentane. Good catch though. I was thinking the same thing.

Just caught it as well!

At 5.32 can we put one group on the top and the other group at the bottom ? rather than two groups on the top ?

You are awesome.... Helping a lot i don't know how to express it but all i can say you is u r love man ❤️❤️❤️

How come there were any ethyl groups when trying to find the isomers?

You are the best, you just made me understand this topic🙂

are cyclo alkanes consitutional isomer?

How would you name the 4-carbon isomer for heptane? The C7H16 molecule? I've named the rest for this one...

2,2 Dimethyl-3MethylButane.

At 4:17 you wrote 2,2-dimethylpentane. Why is it pentane and not propane? You marked 3 carbons on your parent chain

you are right. there's a small error.

7:20 For heptane isnt there the possibility of forming 3- ethylpeptane? Having a five carbon chain with ethyl on the third carbon

But then the main chain will change and hence we will get the same name

bruh this guy probably eats carbon atoms.....amazing video.

is there a general formula to identify the total number of constitutional isomers?

I think this formula it’s work (2^n-4 +1)n:means the number of carbon

Really helpful!! Thank you :-)

you are missing 3-ethylpentane, the 9th isomer of heptane

Heptane has 9 isomers , i think you missed 3 carbon with 2 carbons having 2 carbon branch each , correct me if I'm wrong

Yaaa ur right

You are wrong heptane have 9 isomers but you only write 8 of them, but i admire your work that in great.

Can't we add an ethyl isomer in heptane (3-ethylpentane)?

@@amitojsinghgrover2494idk about the name, but that chain isn't shown in the video and it should be possible as a functional isomer also it would be 3-ethylpentane because you always choose the longest chain and in this case it's 5

Hosam Mohamed It's 2,2-dimethylpropane

Heptane forms 9 and octane forms 18 isomers

i thought nomenclature cannot be the same

The third constitutional isomer of C5H12 is 2,2-dimethyl propane,not 2,2- dimethyl pentane as you have illustrated......nice presentation though
