Explicação
## Step 1: Understanding Allotropic Forms
### The question involves two allotropic forms of carbon: diamond and graphite. Each form has distinct properties due to differences in atomic structure and bonding.
## Step 2: Analyzing the Table Data
### From the table, we see that diamond is hard, conducts heat but is an electrical insulator. Graphite, on the other hand, is soft, does not conduct heat well, but is a good conductor of electricity.
## Step 3: Relating Properties to Hybridization
### The hardness and insulating properties of diamond are due to its three-dimensional tetrahedral structure where each carbon atom is \mathrm{sp}^{3} hybridized, forming strong covalent bonds with four other carbon atoms.
### Graphite's softness and electrical conductivity arise from its planar structure where each carbon atom is \mathrm{sp}^{2} hybridized, forming layers that can slide over each other. The delocalized electrons between these layers allow for electrical conduction.
## Step 4: Matching Hybridization with Options
### Based on the above analysis, diamond corresponds to \mathrm{sp}^{3} hybridization, and graphite corresponds to \mathrm{sp}^{2} hybridization.
