@@schoolaaNo sir..You are right in your own way bcz I saw You told in comment section that you are talk about instead of geometrical isomers ..I'm answering to Karam mahammad sir.. by calculating the of geometrical also like .,2-penten has Z and E and in cyclopropane --RR,SS,SR are there..so total will be 13
Usually they don't ask about isomers for a name, they give a molecular formula and then they ask how many isomers you can draw! Only one structural isomer is named 3,6,6-trimethyl-2-heptene, but if your question is about isomers of C10H20 then there will be alot
Because you are supposed to start numbering the longest chain from the end closer to the substituent, draw it your self and try to number the carbon atoms
I think it's difficult to mix structural isomers with geometric isomers.1-pentene, 2-pentene, 3-methyl-1-butene and methylcyclobutane all have 2 geometric isomers for sure

@@schoolaa plz give your last vedio link and I have also other question if there possible cis trans isomer of propene then can i count cis trans in total isomer?
You are the best! Greetings from Paraguay
Thank you 😊
Thank you so much your videos have helped me a lot!
You are most welcome dear 😊💐
One day before exam, such videos really help a lot.
I wish you all the best 😊
Thank you so much sir😊love from India😊♥️
You are most welcome dear 💐
Hi , Thanks for the video , My instructor said there are 12 . (University of northern British Colombia) Thanks
Thank you for your comment, would you please write the names of the other isomers?
by the way, here i'm drawing all the structural isomers not the geometrical isomers :)
mine said 11: pentene, trans-2-pentene, cis-2-pentene, 2-methylbutene, 9-methylbutene, 2-methyl-2-butene, cyclopentane, methylcyclobutane, ethylcyclopropane, 1,1-dimethylcyclopropane and 1,2-dimethylcyclopropane.
Trans and cis are not considered structural isomers, they are called stereoisomers!! If you want to count them you will get more than 11
@@schoolaa oh ok I guessed on the names but my teacher said there’s 11 🤷♀️
Very much help ful, 😌

What about cis and trans (1,2-dimethylcyclopropane)
it's 2 different isomers
so we have 11 different isomers for C5H10
Thanks a million 😊😊
Thank you Karam, here I'm showing the structural isomers only, cis and trans are geometrical isomers 😉
The molecule has 13 stereoisomer in total
Are you sure?

I have a question if possible...
how many positional isomers are possible for the following molecular ( 3,6,6- tertmethyl -2-heptane )?
I didn't get your answer Mona, how 2-heptane?!
@@schoolaa sorry l meant 3,6,6-tertmethyl -2-heptene
Usually they don't ask about isomers for a name, they give a molecular formula and then they ask how many isomers you can draw!
Only one structural isomer is named 3,6,6-trimethyl-2-heptene, but if your question is about isomers of C10H20 then there will be alot

sorry but I didnt really get why 3 methyl 2 butene isn't possible as isomers?
Because you are supposed to start numbering the longest chain from the end closer to the substituent, draw it your self and try to number the carbon atoms
Like amigo❤
🌹
Thank you!
Most welcome
why cant there be cyclic aldehydes? as its dou is 1
Aldehydes functional group is carbon double bond O and one bond with H, how this can be possible to be cyclic
Thanks ✅
You are most welcome 😊
What about the possible isomers for alkyne with formula n=5? Thanks if you answer 🙏
Dear, there are only three alkyne isomers for C5H8, but in case you want all the possible isomers it would be too difficult
Since you have to think of dienes, cycloalkanes and cycloakenes ... many possibilities 🤔
Thanks for answering.😊
Is there any way I can show you how I did it? Because I’m not sure if I have it right?
You are most welcome 😊
Thank you very very much l had an exam there was this question I did it 10 but l was not certien but now l'am

👍🏻😊 I have another channel in Arabic "Schoolaa بالعربي"
@@schoolaa Can I know its link ,are you Arabic?
ruclips.net/channel/UCSVtFxBp6R5WLJ0wSfSFL1g
How can I identify where double bonds should be drawn?
Wherever it is possible do it, this is the idea of isomers
@@schoolaa Thanks! It help me to understand isomer better!
Wish you all the best dear 🙂
is the type of isomer a functional group isomerism?
You can say this, since the double bond can be considered as the functional group for alkenes
Thnks
👍🏻
Plz draw all the possible isomers of c5h8
👍🏻
plz tell is methyl cyclobutane will be an isomer of pentene
Methylcyclobutane is an isomer for C5H10
We can not say isomer of pentene, since pentene is also an isomer for C5H10
@@schoolaa thankyou sir
😊👍🏻
Others say that it's isomers is 13 or 12
They didn't not include cyclic
I'm from Malaysia
Welcome to your channel 🌹
🥰🥰🥰❣️🧡🧡
💐🙂
I'm sorry sir, I want to ask something
So, total, with geometry isomers, there are 13 isomers of pentene?
I think it's difficult to mix structural isomers with geometric isomers.1-pentene, 2-pentene, 3-methyl-1-butene and methylcyclobutane all have 2 geometric isomers for sure
My last video is talking about cis and trans, in case you wana watch 😊
Thank you Sir, I am watching it
But, what is the difference between (1S-trans)-1,2-dimethylcyclopropane and
(1R-trans)-1,2-dimethylcyclopropane?
Your last video doesn't explain that
Can we dwaw 6th open chain isomer of this.
No, it has only five carbon atoms
From which country you are watching?
The mother land. Russia
😊
@@schoolaa India
👍🏻😊
I"m from Russia too
hi, thanks for the video..what about cis trans isomers?
Check my newest videos 😊 explaining cis trans in details
@@schoolaa okay tysmm
How many geometric isomers does c5h10 has..?
I think it's difficult to mix structural isomers with geometric isomers.1-pentene, 2-pentene, 3-methyl-1-butene and methylcyclobutane all have 2 geometric isomers for sure
You may watch my latest videos about geometric isomers

Are you from Egypt🧐
No 😉
@@schoolaa then?🥲
Why not 1ethyl 2butene
We can't have substituents or branches at the end carbons
3 methyl but 2 ene
You can not have it, when the double bond is at the middle, then you should count closer to methyl
I want help
In what?
how many isomer ofC3H6 plz explain?
Only two structural isomers: propene & cyclopropane
@@schoolaa sir is there any possibility of geometric isomerism?
Yes for sure, in the case of propene you have cis and trans
You may watch my last video for more details
@@schoolaa plz give your last vedio link and I have also other question if there possible cis trans isomer of propene then can i count cis trans in total isomer?

😊🌹
draw all the possible isomers of c7h10
There are alot, maybe three double bonds, maybe double and triple, maybe cyclic with two double..., many possibilities you need an hour long video 😉
The first 6 isomers of C7H10 and C5H10
