AP Chemistry Thou Shall Not Forget- Part 1

Front

What is a sigma bond?

Back

A sigma bond is a type of covalent bond formed by the direct overlap of atomic orbitals, allowing for free rotation around the bond axis.

Front

What is a pi bond?

Back

A pi bond is a type of covalent bond formed by the side-to-side overlap of p orbitals, which restricts rotation around the bond axis.

Front

How many sigma and pi bonds are in a double bond?

Back

A double bond consists of 1 sigma bond and 1 pi bond.

Front

Under what conditions do real gases behave most like ideal gases?

Back

Real gases behave most like ideal gases at high temperatures and low pressures.

Front

What is the Lewis Dot structure for PCl5?

Back

The Lewis Dot structure for PCl5 shows phosphorus in the center with five chlorine atoms surrounding it, indicating a trigonal bipyramidal geometry.

Front

What is the predicted molecular geometry of PCl5?

Back

The predicted molecular geometry of PCl5 is trigonal bipyramidal.

Front

What type of bonds break when a molecular solid melts?

Back

When a molecular solid melts, intermolecular bonds break.

Front

What does the height of a peak in a PES graph represent?

Back

The height of a peak in a PES graph represents the number of electrons in that energy level.

Front

What is the difference between intermolecular and intramolecular bonds?

Back

Intermolecular bonds are forces between molecules, while intramolecular bonds are forces within a molecule.

Front

What is the significance of high temperature in gas behavior?

Back

High temperature increases the kinetic energy of gas molecules, making them behave more ideally.
