(a)
Interpretation:
The direction of polarity with d+ and d- in Si-O and Si-Si bonds should be labeled.
Concept Introduction:
A
The C-C and C-H bonds are nonpolar covalent bonds as the difference between the electronegativity of C and H are very less. On the contrary, the polarity of the C-X bond depends on the electronegativity of X. If X is O, N or halogen, the C-X bond will be a polar covalent bond that makes the polar organic molecule.
(b)
Interpretation:
The direction of polarity with d+ and d- in H-F and H-Br bonds should be labeled.
Concept Introduction:
A chemical bond is formed between two atoms by sharing of electrons or by transferring the valence electron. On the basis of the electronegativity of bonded elements, the covalent chemical bond can be polar and non-polar in nature.

(c)
Interpretation:
The direction of polarity with d+ and d- in C-B and C-Li bonds should be labeled.
