# Ok, I give up, What is -Et?

#### amb123

I can't figure it out. I missed this somewhere, and got by with just figuring it as an -R group, but is it some specific group?

Such as epoxy ---(alkoxy & EtOH) ---> n-alkoxy alkanol

Where the hell did I miss this, it seems everywhere in my book now that i'm studying for the ACS exam, but I can't find where the explanation is.

thx!
-A

Ethyl. H3CH2C-

It's an informal shorthand that is fairly popular.

And don't come back if you see a Me- group somewhere...

Or Ph- for that matter :)

Thanks! I knew of the phenyl group shorthand, but not ethyl. Lucky for me, I was just treating the -Et as -R and it worked out ok;) Thanks for the tipoff on methyl with -me, I guess ch3 is really MUCH longer! lol!

That's old school. Not many people use that anymore. Sure is convenient though!
