Accepted Answer

All right. Hi everyone. So this question says to provide the structure of ethel propionate and use dash lines to show the sites where it forms hydrogen bonds with other similar molecules. So in this case, right, the compound in question, eop propionate is in fact an ester. Now recall that ethers are functional groups that are derived from carboxylic acids and alcohols combining together. So in this case, the ocho group coming from the alcohol is treated as a substituent written before the parent chain. So naturally the parent chain is what originates from the carboxylic acid portion of the ester. So in the case of the name we are given right, the substituent is ethel and the parent chain is propionate. And for that matter, right? The reason why I was able to identify this as an ester is because notice how the suffix of the parent chain is oate as opposed to simply an e after the end of the parent chain, that suffix is characteristic of an era. So in this case, the parent chain is in fact propionate which is a three carbon chain with a car bono at the very end, right? So attach that carbel is another oxygen from the alcohol portion of our ester. And so attached to the oxygen from our alcohol is an ethyl group or a two carbon chain. So this would be the structure, right? But now the question is, does this compound exhibit hydrogen bonding at all? And to understand this, we have to understand what hydrogen bonding actually is. Recall that hydrogen bonding or h bonding for short requires a hydrogen that is bound to a highly electron atom. For example, nitrogen oxygen or fluoride. Now a common example of a functional group capable of hydrogen bonding or alcohols which contain hydroxy or oh groups attached to carbon chains. Now, in this case, we have a hydrogen connecting to a highly electron atom, specifically oxygen. So if we consider two alcohol molecules interacting with each other, right, then hydrogen is going to interact with the highly electron oxygen and vice versa. So hydrogen is the hydrogen bond donor and oxygen is the hydrogen bond acceptor. So if we consider the structure of our ester, notice how neither oxygen present in the structure of our ester contains hydrogen. So because of this, right, it simply cannot exhibit hydrogen bonding because neither oxygen has a hydrogen that's able to form hydrogen bonds with other molecules and there you have it right. So here is the structure of ethyl propionate. And due to the nature of its structure, it does not exhibit hydrogen bonding. So with that being said, thank you so very much for watching. And I hope you found this helpful.
