Electronegativity - Homework

Which of the following bonds would be the least polar yet be considered polar covalent?

• Mg–O

• C–O

• O–O

• Si–O

• N–O

Which of the following bonds would be the most polar without being considered ionic?

• Mg–O

• C–O

• O–O

• Si–O

• N–O

Which type of bond is created between C-N?

• Polar Covalent

• Non-polar Covalent

• Ionic

• Metallic

A bond with a partially negative end and a partially positive end is:

• ionic
• polar
• non-polar
• isometric

Which is the least polar bond?

• HCl
• HF
• OH
• H₂

If the atoms that share electrons have an unequal attraction for the electrons, the bond is called

• nonpolar
• polar
• ionic 
• dipolar

In this Lewis structure, the symbol above F means...

• electrons are being transferred to Fluorine
• electrons are less attracted to F than H
• electrons are more attracted to F than H
• Fluorine has formed a cation

In the polar covalent molecule of hydrogen chloride (HCl) - the chlorine atom has

• a lesser pull on electrons and therefore a positive charge.

• has a greater pull and therefore a negative charge.

• has no effect on charge because it is neutral.

• a lesser effect on valence electrons.

Electronegativity is a measurement of the ability of a nucleus to...

• attract bonding electrons
• attract other nuclei
• attract elenece in the non-valence energy levels

Which of the following molecules would most likely exhibit hydrogen bonding?
