Bond Polarity

Front

What type of bond forms when Boron bonds with Hydrogen, given their electronegativity values?

Back

nonpolar covalent

Front

What is the first step in determining bond polarity?

Back

Compare the electronegativity (EN) values of each bonding atom.

Front

In covalent bonds, how are electrons treated?

Back

Electrons are shared.

Front

In a polar covalent bond, how are electrons shared?

Back

Unequally.

Front

What are partial charges in a molecule called?

Back

Dipoles.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a bond.

Front

What happens to the electron density in a polar covalent bond?

Back

The electron density is unevenly distributed.

Front

What is the significance of a dipole moment in a molecule?

Back

It indicates the polarity of the molecule and the direction of the dipole.

Front

How does the difference in electronegativity affect bond type?

Back

A large difference leads to ionic bonds, a small difference leads to covalent bonds, and no difference leads to nonpolar covalent bonds.

Front

What is the range of electronegativity values for nonpolar covalent bonds?

Back

0 to 0.4.
