Polar and Non-Polar Bonds

The video tutorial explains ionic and covalent bonds, focusing on electron transfer and sharing. Ionic bonds involve electron transfer between metals and non-metals, resulting in charged ions. Covalent bonds involve electron sharing, with non-polar bonds having equal sharing and polar bonds having unequal sharing, leading to partial charges. The video compares bond polarity, highlighting that ionic bonds are more polar than covalent bonds due to greater electronegativity differences.

What is the primary characteristic of an ionic bond?

• Equal sharing of electrons

• Transfer of electrons

• No electron movement

• Formation of a dipole

Which type of bond involves the sharing of electrons?

• Hydrogen bond

• Metallic bond

• Covalent bond

• Ionic bond

What is the range of electronegativity difference for a non-polar covalent bond?

• 1.1 to 1.5

• 1.6 to 2.0

• 0.5 to 1.0

• 0 to 0.4

In a non-polar covalent bond, how are electrons shared?

• Not shared

• Unequally

• Transferred

• Equally

What causes the partial charges in a polar covalent bond?

• Equal sharing of electrons

• Unequal sharing of electrons

• No electron movement

• Transfer of electrons

Which atom in a polar covalent bond tends to have a partial negative charge?

• The atom with higher electronegativity

• The atom with fewer electrons

• The atom with more protons

• The atom with lower electronegativity

Which bond is more polar: a polar covalent bond or an ionic bond?

• Neither is polar

• Both are equally polar

• Ionic bond

• Polar covalent bond

What is the electronegativity difference in sodium chloride that makes it highly polar?

• Cl2

• NaCl

• HCl

Why is sodium chloride more polar than hydrochloric acid?

• It has equal electronegativity difference

• It has a lower electronegativity difference

• It has a higher electronegativity difference

• It has no electronegativity difference
