Concept explainers
(a)
Interpretation:
Lone pairs around N and O atoms should be added in the given structure of glyphosate.
Concept Introduction:
A Lewis structure, in contrast, shows the connectivity between the atoms, as well as where all
the bonding and nonbonding valence electrons reside.
Most of the common elements in covalent compounds-carbon, nitrogen, oxygen, and the
halogens-generally follow the octet rule. Hydrogen is a notable exception, because it
accommodates only two electrons in bonding.
(b)
Interpretation:
Number of electrons around the P in the structure of glyphosate should be calculated.
Concept Introduction:
A single covalent bond is formed by equal sharing of 2 electrons and a double covalent bond is formed by equal sharing 4 electrons.
(c)
Interpretation:
Atoms in glyphosate that do not follow the octet rule should be determined.
Concept Introduction:
In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained either by sharing of electrons or complete transfer of electrons. The tendency of atoms to attempt to get a noble gas configuration that is eight valence electrons is said to be octet rule.

- Although I3- is a known ion, F3- is not. (a) Draw the Lewis structure for I3- (it is linear, not a triangle). (b) One of your classmates says that F3 - does not exist because F is too electronegative to make bonds with another atom. Give an example that proves your classmate is wrong. (c) Another classmate says F3- does not exist because it would violate the octet rule.Is this classmate possibly correct? (d) Yet another classmatesays F3- does not exist because F is too small to make bonds tomore than one atom. Is this classmate possibly correct?arrow_forward18.) Choose all the statements that are correct. (1) Like atomic size, electronegativity decreases going across a period and increases going down a group. (2) The second most electronegative element is chlorine. (3) Electronegativity is directly proportional to atomic number. (4) Like ionization energy, electronegativity increases going across a period and decreases going down a group. (5) Electronegativity is a measure of the ability of an atom to attract electrons and form a negative ion. (6) Electronegativity is a measure of the ability of an atom in a molecule to attract electrons go itself. (7) Electronegativity was first proposed by Linus Pauling.
