Nucleophiles and Electrophiles Crossword
Down
:
1) or resonance effect describes the electron withdrawing or releasing properties of substituents based on relevant resonance structure.
3) the effect exerted by a substituent on modifying electrostatic forces operating on a nearby reaction center. (electronic)
4) a reagent that forms a chemical bond to its reaction partner by donating both bonding electrons.
5) special type of nucleophilic substitution where the nucleophile is a solvent molecule.
6) make better leaving groups
7) fundamental class of reaction in which an electron rich nucleophile selectively attacks the positive charge of an atom bound to the leaving group which subsequently departs.
10) reaction in which a functional group in a particular chemical compound is replaced by another group.
12) reaction where a pi bond is removed by creating two new covalent bonds by the addition of a nucleophile.
13) leaving group which retains the lone pair from its previous bond with another species.
17) leaving group which does not retain the lone pair from its previous bond with another species.
18) an organometallic chemical reaction involving alkyl- or aryl-magnesium halides with electrophiles.
Across
:
2) an atom or group of atoms that detaches from a chemical substance.
8) increased nucleophilicity of a molecule due to the presence of an adjacent atom with lone pair electrons.
9) relative tendency of a charge distribution, like the electron cloud of an atom or molecule, to be distorted from its normal shape by an external electric field.
11) substitution reaction involving nucleophiles and acyl compounds.
13) Lewis bases
14) a special type of nucleophilic aromatic substitution in which a nucleophile replaces hydrogen and not an expected substituent like a halogen.
15) a reagent attracted to electrons that participates in a chemical reaction by accepting an electron pair in order to bond
16) a valence electron pair without bonding or sharing with other atoms.
19) an experimentally observable effect of the transmission of charge through a chain of atoms in a molecule by electrostatic induction.
20) addition reaction where, in a chemical compound, a pi bond is removed by the creation of two new covalent bonds.
21) a reaction in organic chemistry in which the nucleophile displaces a leaving group, such as a halide, on an aromatic ring.
