If its a double bond it should be -CH=CH-CH3. It may be a triple bond. But books don't usually omit the double bond or triple bond when writing straight line formulas. Perhaps that just a printing error. If it has a name you will know which it is.

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 how a carbon can be ...

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 ...

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 is ...
