Front

How is the bond between carbon (C) and fluorine (F) represented?

Back

The bond between C and F is represented as a single or double line, depending on whether it is a single or double bond.

Front

Which molecular shape has the smallest bond angle around the central atom?

Back

The bent shape with two lone pairs has the smallest bond angle.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the shape and bond angles of a molecule.

Front

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs.

Front

What is the bond angle in a trigonal planar molecule?

Back

The bond angle in a trigonal planar molecule is approximately 120 degrees.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.
