Halogenated substituents on a benzene ring remove electron density by resonance, but can donate electron density by induction. Gringnard reagents are compatible with acids. ____An ether is more reactive than an alcohol. In the Diels-Alder reaction, the diene has electron-density attracting groups while the dienophile has electron-density donor groups. __An alkoxide is a weak nucleophile. The s-trans conformation for a diene is more stable than the s-cis conformation. The boiling point of disubstituted benzenes increases with a decrease in polar moment.
