Which of the following bonds is present in diamond? MCQ with Answer and Explanation

Question
Which of the following bonds is present in diamond?
A. Hydrogen bond
B. Metallic
C. Ionic
D. Covalent network
Answer: Option D
Solution (By JKExamLibrary)
Diamond has a three-dimensional network of strong covalent bonds between carbon atoms (sp³ hybridization). This giant covalent structure gives diamond its extreme hardness, high melting point, and electrical insulating property. Graphite also has covalent bonds within layers but conducts due to delocalized electrons. Ionic bonds are in NaCl, metallic bonds in metals, hydrogen bonds in water.

Correct Answer: Option C

Explanation:
Mg goes from 0 to +2 oxidation state, losing electrons – oxidized. Oxygen is reduced (0 to -2). This is a combustion/combination redox reaction.

Correct Answer: Option B

Explanation:
The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances responsible for ozone depletion, most notably chlorofluorocarbons (CFCs). Both statements are correct, and R perfectly explains the purpose of the protocol.

Correct Answer: Option B

Explanation:
Magnesium oxide (MgO) is an ionic compound. Magnesium (2,8,2) loses two electrons to become Mg²⁺, and oxygen (2,6) gains two electrons to become O²⁻. This electron transfer forms an electrovalent (ionic) bond. Covalent bonds involve sharing (e.g., H₂O).
