Let's review concepts that we discussed in class today. Identify whether the following statement is true or false. The Diels-Alder reaction is stereospecific. Cis dienophile forms cis-substituted cyclohexene. Trans dienophile forms trans-substituted cyclohexene. Methoxy group (OMe) is an electron-donating group. An electron-withdrawing group can be identified by a formal or partial positive charge on the atom directly attached to the dienophile. Nitro group (NO2) is an electron-donating group. The reactivity of dienophile increases in the presence of electron-donating group
