I decided to go back to my organic chemistry and the thing wan scatter my brain. What's the name of this compound?

2-ethyl,3-methyl but-2-ene

2-Ethyl-3-Methyl-2-butene or 2-Ethyl-3-Methylbut-2-ene

2,3 dimethyl pent-2-ene

BIGPREEQ:
2-Ethyl-3-Methyl-2-butene or 2-Ethyl-3-Methylbut-2-ene

there is nothing like ethyl In that compound, the longest chain self is pent-2-ene not but-2-ene, I don't know how u and the guy above u are numbering carbon atoms but I am a chemistry teacher, and if my students give me 2,3 dimethyl pent-2-ene or 2,3 methyl pent-2-ene, I will mark it.....that's the only two names that can represent this compound

check ur options and mark it there is only two names that can represent the compound...
2,3 dimethyl pent-2-ene or 2,3 methyl pent-2-ene

namiji2598:
2,3 dimethyl pent-2-ene

clap clap

I studied chemistry, am also a chemistry teacher, it would have been my pleasure to see you through this course, but time and distance is a barrier here....

PrinceAlaba:
2-ethyl,3-methyl but-2-ene

Incorrect

The longest chain is 5. It has double bar (bonding) at 2. That's Pent-2-ene ( Alkenes family)

Ch3 (methyl) attached to carbon 2 &3

Hence, the name = 2,3 dimethyl pent-2ene

namiji2598:
2,3 dimethyl pent-2-ene

You must be good in organic chemistry. I go with you, bro

Thanks guys. O really appreciate.

By SS2, I had already made up my mind I was studying Civil Engineering, so when Master Achinze the Chemistry Master was doing all those his Aromatic and Aliphatic compounds shenenegans, I was doing better things with my precious time.

Just imagine that those who even know what this is are arguing among themselves what the real name is. Who has that kind of time Biko?

2,3-dimethyl pent-2-ene or 2,3-dimethyl 2-pentene...

namiji2598:
2,3 dimethyl pent-2-ene

this is correct.

Longest chain is 5, with the double bond makes it from the alkene family and its on on carbon -2


2,3-dimethyl pent-2-ene

The bolded is wrong because 2,3 depicts there are 2 methyl group attached. Thus should be 2,3-dimethyl-2-pentene. That should be the second possible name

correct and detailed

let me teach you a trick. once you finf out the longest carbon chain, any carbon that is nit part of that chain is treated as a substituent.

yes ofcus there are two methyl group in that compound, and the methyl compound is on 2,3
There is nothing wrong in that compound name, either 2,3 dimethyl pent-2-ene or 2,3 methyl pent-2-ene

Single, double and triple bond.
I love this topic..

2,3-dimethyl pent-2-ene

Your head is very correct.

abeg I left this shit in my 2 year. As I pass organic chemistry I tell am bye bye

namiji2598:

There is nothing wrong in that compound name, either 2,3 dimethyl pent-2-ene or [b]2,3 methyl [/b]pent-2-ene

Quote me anywhere, the bolded is totally wrong.

When you quote more than one attached group of the same family it is a must you add the prefix be it di-, tri- etc

You can't say 2,3- methyl... Its is wrong 2,3-dimethyl.... Is correct

2,3,4- trimethyl correct... 2,3,4 methyl is wrong

There are 2 carbons carrying methyl group thus the prefix should be Di- you cannt omit that and say the nameis correct no.

pardon me bro, but How many degrees do you have bro?
Seem your comment on Some technical topics over the Years here on NL, or are you a Science teacher?

nawa oo I can't believe my eyes.someone is saying the longest chain is 5 and claiming to av read chemistry.The correct answer is the first person that commented.The longest chain is 4 that is but-2-ene.

PrinceAlaba:
2-ethyl,3-methyl but-2-ene

correct!
