Somebody already asked this question about a month ago (see this post: http://forums.studentdoctor.net/showthread.php?p=3856355#post3856355) but no one really answered the question. On Topscore test 1 #76 (ochem) the answer is A but from what I understand, heat must be added for the OH to leave as water and make a C=C. Does anybody know if that is true? If so, shouldn't the answer be E? I checked Topscore's website to see if they corrected the mistake but it does not address the issue. Help please!
