Chemistry: Principles and Practice
For central atoms that have lone pairs, the bonded-atom lone-pair arrangement
differs from the molecular shape. ... (a) The bonded-atom lone-pair arrangement
of water is tetrahedral, with two lone pairs and two bonding pairs. (b)The ...

Chemical Structure and Bonding
Next we consider the SF4 molecule which has four bond pairs and one lone pair
surrounding the sulfur atom. Where should we place the lone electron pair in SF4
? According to the VSEPR method, the most prohibitive repulsion is (lone ...

... top line of Figure 8.8 show species having a total of five valence electron pairs,
with zero, one, two, and three lone pairs. In SF4, with one lone pair, the molecule
assumes a “seesaw” shape with the lone pair in one of the equatorial positions.

Principles and Applications of Stereochemistry
formed, the distance (i.e. angle) between the lone pair and the bond pairs is
considered (rule 3), since these groups repel one another more strongly than
bond pairs repel other bond pairs. In structure 1.27a, there are two bond pairs at
90° to ...

According to the VSEPR method, the most prohibitive repulsion is (lone
pairHlone pair), followed in order by (lone pair)-(bonded pair) and (bonded
pairMbonded pair). Therefore in SF4 the "worst" repulsion is (lone pairHbonded

Electron source A bond or lone pair of electrons, usually an area of relatively high
electron density, that serves as the origin of a mechanism arrow. An electron
source characteristically interacts with an electron sink in an organic mechanism.
William Brown, Christopher Foote, Brent Iverson, 2011

The Basics of Chemistry
Many times the central atom contains a single lone pair or lone pairs of electrons
in addition to bonding pairs. The presence of lone pairs, which occupy more
space than bonding pairs, affects the repulsive forces between the valence
electrons ...

ADV IN CARBOHYDRATE CHEM & BIOCHEM
2. Lone-Pair Orbital Interactions in Reactivity The lone pairs of oxygen atoms are
the least strongly bound atomic orbitals, and thus are localized prevailingly in the
highest-occupied MO's. Hence, it is natural that lone pairs play a central role in ...

Principles of Chemistry: The Molecular Science
In the case of NH3, there are three bonding pairs and one lone pair; thus, NH3 is
an AX3E1-type molecule (Table 9.1). If there were multiple bonds, any electron
pairs in a multiple bond would contribute to the molecular geometry as those in a
...
