Molecular Structures and Bonding Patterns Quiz

#1

What is the shape of a molecule with a trigonal planar molecular geometry?

Trigonal planar
Explanation

Three bonding pairs, no lone pairs, 120-degree bond angles

#2

Which type of bond involves the sharing of electrons between atoms?

Covalent bond
Explanation

Electron sharing between atoms to achieve stability

#3

Which type of bond is formed due to the electrostatic attraction between ions?

Ionic bond
Explanation

Transfer of electrons from one atom to another, resulting in oppositely charged ions

#4

What is the bond angle in a molecule with a trigonal pyramidal molecular geometry?

107 degrees
Explanation

Lone pair repulsion causing a slight deviation from the ideal 109.5 degrees

#5

Which type of bond is formed by the sharing of electrons equally between atoms?

Covalent bond
Explanation

Equal sharing of electron pairs between atoms

#6

What is the hybridization of carbon in methane (CH4)?

sp3
Explanation

Four electron pairs, tetrahedral geometry

#7

Which of the following molecules exhibits polar covalent bonding?

H2O
Explanation

Asymmetric electron distribution due to oxygen's higher electronegativity

#8

What is the geometry of a molecule with two bonding pairs and two lone pairs on the central atom?

Bent
Explanation

Electron repulsion causing a distortion from linear, resulting in bent shape

#9

Which of the following bonds is the weakest?

Hydrogen bond
Explanation

Weak attraction between a hydrogen atom and an electronegative atom

#10

What is the hybridization of oxygen in water (H2O)?

sp2
Explanation
