Regents Chemistry Bonding Review

Front

What is the most polar bond between two atoms?

Back

The bond between H and O (H-O) is the most polar.

Front

Which element has the strongest attraction for electrons in a chemical bond?

Back

Chlorine has the strongest attraction for electrons.

Front

Why do hexane and water separate into two distinct layers?

Back

They have different molecular polarities.

Front

What diatomic molecule is formed when two atoms share six electrons?

Back

N2 (Nitrogen gas) is formed when two nitrogen atoms share six electrons.

Front

How is the charge distribution and polarity of a CH4 molecule described?

Back

CH4 is symmetrical and nonpolar.

Front

Define polarity in the context of chemical bonds.

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has an even distribution of charge, resulting in no distinct poles.

Front

What is a polar molecule?

Back

A polar molecule has an uneven distribution of charge, leading to distinct positive and negative poles.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond.

Front

What type of bond is formed when electrons are shared equally?

Back

A nonpolar covalent bond is formed when electrons are shared equally.
