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