Since 3 member ring is quite strain, it is reactive. <br /><br />The nucleophile CH3CH2O- attacks the three member ring to form the product. Is that correct?WEiJiEhttps://www.blogger.com/profile/12827877360760319834noreply@blogger.comtag:blogger.com,1999:blog-4162288248021721977.post-83619151739593806922013-07-14T03:17:42.064-07:002013-07-14T03:17:42.064-07:00Yes, there is a cylic intermediate.
