Interpretation:
The statement for bond line given in the Lewis structure characterization that is incorrect has to be chosen from the given options.
Concept Introduction:
Sharing of electrons that is associated with covalent bond formation can be visualized using the Lewis structure. Covalently bonded atoms contain bonding and non-bonding electrons.
The valence electrons that are shared between the atoms in covalent bond is known as Bonding electrons. Dashes are used to represent the pair of valence electrons that are shared between the atoms.
The valence electrons that are not involved in the electron sharing is known as Nonbonding electrons. These are also known as lone pair of electrons or unshared pair of electrons. These electrons play a major role in geometry of molecules.
Atoms are involved in sharing of the valence electrons in order to attain the stable octet configuration. Hydrogen atom has only one electron in it and hence octet is not possible for hydrogen atom alone.

- The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forwardWhich of the following represents a covalent interaction? Choose any/all answers that apply.

- Draw all three staggered conformations for the following compound, viewed along the C₂-C3 bond. Determine which conformation is the most stable, taking into account gauche interactions and hydrogen-bonding interactions. (J. Phys. Chem. A 2001, 105, 6991-6997) Provide a reason for your choice by identifying all of the interactions that led to your decision. H H&COH C₂ C3 HỌ CH CH3 Which of the following is the most stable staggered conformer? Me H OH Me OH Me- Me Me H Conformer A OH OH OH HO H H H Conformer B Conformer C Me Conformer B because the anti OH groups avoid hydrogen bonding, which is a destabilizing effect. Conformer A because there are only two gauche interactions, and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer C because there is no steric strain for Me-OH gauche interactions and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer B because the large OH groups are anti to each other.arrow_forwardWhich of the following correctly describes peptide bonds? * A. They are a special type of amide bond. B.
