Concept explainers
(a)
Interpretation:
To draw a condensed structure for an alcohol having molecular formula
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 O 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
