I have a problem drawing this formula. CH3CH2CH2CH(CH3)CCCH3 The problem is the 2 c's next to each other. I don't know what that's supposed to look like since if it's 1 CH like with the bracketed CH3 it would be connected to that C but I'm confused as to ...

There is more than one use of the Grignard reaction to prepare each of these. In practice you would consider cost of starting materials and ease of separation of the product(s) from starting materials. I assume we are going to use the original Mg based version rather than any ...

this is considered to have asymmetrical carbons :ch3ch2ch(chlorine group is connected on bottom)Ch3 why isn't this one: ch3ch2ch (methyl group attach to it) ch3? By convention, we look at the carbon chains, and carbon sidechains when discussing symettry. If the second were...

.............Br .............| CH3 - CH2 - CH - CH2 -CH3 .............| ..........CH2CH3 This is what I meant to draw. The Br and ethyl group just shifted over after I clicked post answer. So would this be 3-bromo-3-ethylpentane

a. You've drawn 1-butene with groups hanging from it. You have only two methyl groups but the name has three. And you place the two methyl groups on the 2-carbon. You start numbering from the double bond. Finally the terminal CH3 on the right has a five-valent carbon which...

On the topic of esters, if my Ester is CH3-C(double bond directly downward below the C)-O-CH3, would it be methyl ethanoate or methanoate ethyl? Thanks.

CH3 - CH2 - CH (which has a Br and ethyl group off of it) - CH2 - CH3 - so basically the Br and CH2CH3 shift over to the CH

Hey, thanks a lot. Yes, sorry I did write those incorrectly.Here they are: 11. CH3--CH--C--CH3 OH is above the CH O is above the C _________________________________ So 15. does have four separate groups? 15. CH3--CH--C--CH3 CH3 is above the CH O is above the C

n means normal, which means it is a single chain, no branches. CH3-C*C-CH3 where * means a triple bond The proper name for this is 2-butyne. There is another butyne, 1-butyne. Both are straight chains. The use of normal here is not proper, at least here in Texas.
