The difference in the strengths of theintermolecular forces among methane (C H4 )molecules and ammonia (N H3) molecules ismainly due toA the fact that ammonia is polar and methaneis nonpolar.B the fact that methane is polar and ammoniais nonpolar.C the fact that methane (with four hydrogens)has a greater chance to exhibit hydrogenbonding than ammonia (with threehydrogens).D the different molar masses.
Chapter 7 Leaving groups withdrawal electron density, rendering the adjacent atom (usually 1 carbon) electrophile Leaving groups can stabilize any negative charge that may develop 7.2 alkyl halides Nomenclature ID parent and name substituents Number parent chain and ID location of each substituent Assign substituents, alphabetically, closest to “a” first Every substitution reaction has at least two of the four patterns o Nucleophilic attack o Loss of leaving group o Stepwise mechanism: both occur, but under different conditions o Concerted process: nucleophilic attack and loss of leaving group occurs SIMULTANEOUSLY Uses of organic halides: pesticides, primarily insectic
