ALC 2024 Bonding mini-test Review (I/C/M, VSEPR, IMF)

Front

What is the shape of a molecule with a trigonal pyramidal geometry?

Back

A trigonal pyramidal molecule has a central atom bonded to three other atoms and has one lone pair of electrons, resulting in a pyramid-like shape.

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces.

Front

How is the polarity of a bond determined?

Back

The polarity of a bond is determined by the difference in the electronegativities of the two atoms involved in the bond.

Front

What describes covalent bonding?

Back

Covalent bonding involves the sharing of valence electrons between atoms, which can result in single, double, or triple bonds.

Front

How are electrons shared in an ionic bond?

Back

In an ionic bond, electrons are not shared; instead, they are transferred from one atom to another.

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons and the formation of charged ions, while covalent bonding involves the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is a polar bond?

Back

A polar bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other.

Front

What is a nonpolar bond?

Back

A nonpolar bond is a type of covalent bond where the electrons are shared equally between the two atoms, resulting in no charge separation.
