Write structural formulas for each of the following alcohols and alkyl halides: 

(h) 2-Cyclopropylethanol

Video Transcript

Alright guys. So, in this problem we're doing with two cyclopropyl ethanol. Now, we need to break this down, we have ethanol, which you know is CH2, CH3 OH and we have the cyclopropyl portion, so we can start up by drawing CH2, CH3 and we know there's going to be an OH somewhere there, right? Coming off of that carbon, this is regular ethanol. Now, we know that it doesn't need to be indicated but position one is the one that bears our alcohol, this would be our carbon 2, so now what do you think we're going to be adding on that substituent to our carbon 2. So, here what we're going to do is we're going to erase one of our hydrogens and this is going to become a two and then indicate that we have a cyclopropyl group coming off of that carbon. Now, I drew it in the structural formula but maybe it would be helpful to convert this to a formula that you're more used to seeing, where you have OH, CH2 and then you have your ring like that, okay? So, and we're actually missing a carbon, so let's indicate that, we have CH2, CH3 and then we have our ring, okay? So this would be your CH2, CH2 this would be your carbon number 1 and this would be your carbon number 2 with your substituent, okay? So, our answer the one this problem asking for, the structural formula, which would be this one right here, okay? And you can erase the numbers and just indicate that our cyclopropyl group is coming off of position 2 and we have ethanol in our structure as well. Alright, so I hope this made sense, let me know if you have any questions.
