(a)
Interpretation:
To draw a condensed structure for an
Concept Introduction:
Condensed structure is accustomed to composing organic structure in a line of text. It demonstrates all molecules, however, overlooks the vertical bonds and most or all the horizontal single bonds. It utilizes brackets to demonstrate that polyatomic gatherings inside in a formula are joined to the closest non-hydrogen atom on the left side.
(b)
Interpretation:
To indicate all polar bonds present in
Concept Introduction:
The unequal sharing of valence electrons in a bond is called polar bond. Polar bond result when the bond formed between two atoms in which one atom is more electronegative than the other one. One example of polar bond is
In
(c)
Interpretation:
To determine the geometry around the N atom.
Concept Introduction:
The following table should be used while determining the shape around an atom.
Number of groups | Number of atoms | Number of lone pairs | Shape | Bond angle |
2 | 2 | 0 | Linear | |
3 | 3 | 0 | Trigonal planar | |
4 | 4 | 0 | Tetrahedral | |
4 | 3 | 1 | Trigonal pyramidal | |
4 | 2 | 2 | Bent |
(d)
Interpretation:
To determine the drawn compound as polar or nonpolar.
Concept Introduction:
Polar compound is that compound in which polar bonds are present. Bond formed due to unequal sharing of valence electrons is called polar bond. Polar bond result when the bond formed between two atoms in which one atom is more electronegative than the other one. One example of polar bond is

- (a) Determine the formal charge of oxygen in the following structure. If the atom is formally neutral, indicate a charge of zero. (b) Draw an alternative Lewis (resonance) structure for the compound given in part (a). Show the unshared pairs and nonzero formal charges in your structure. Don't use radicals. Formal charge on O 0arrow_forwardOxalic acid, H2C2O4, a poisonous colorless solid, is found in some vegetables such as spinach and rhubarb. It is present in concentrations well below the toxic limit, so you can't use this as a reason to refuse a helping of spinach. The order of atoms in a molecule of oxalic acid is HO2CCO2H.

Because each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCI.
