jian Posted February 9, 2010 Share Posted February 9, 2010 Ether has very similar structure as alcohol. Why there is hydrogen bonding in alcohol but not in ether? Oxygen atoms have two lone pairs in both cases. Link to comment Share on other sites More sharing options...
louis wu Posted February 9, 2010 Share Posted February 9, 2010 Ether has no H atoms directly bonded to electronegative O. It is the H-O bond that produces the [CE]d[/CE]+ partial charge on the H that produces Hydrogen bonding. 1 Link to comment Share on other sites More sharing options...
jian Posted February 9, 2010 Author Share Posted February 9, 2010 Then I have a question about the intermolecular force in PET. Is there any hydrogen bonding between the PET chains? Link to comment Share on other sites More sharing options...
CaptainPanic Posted February 11, 2010 Share Posted February 11, 2010 For a good hydrogen bond, you need an attached H-O. In PET, there are plenty of Oxygens, but none of them have a hydrogen attached directly. http://www.polymerprocessing.com/polymers/PET.html Link to comment Share on other sites More sharing options...
amit Posted February 13, 2010 Share Posted February 13, 2010 here is an example of h bonds between acetone molecules. so in ether it might be there but unsignificantly weak. wikipedia also says about h bonds between acetone http://books.google.com/books?id=be0T64ZWp9EC&pg=PA211&lpg=PA211&dq=manku,+hydrogen+bonding&source=bl&ots=5NxzqpHuhM&sig=BsxXqR1qOlqcH229JBJN8yw6sEI&hl=en&ei=w8J2S5GWK8qwrAf77qT1Dw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CAcQ6AEwAA#v=onepage&q=&f=false sorry o tried but cant upload the specific page tthis time but try page no-213 Link to comment Share on other sites More sharing options...
