Explanation

In graphite, the carbon atoms are arranged in a hexagonal structure.

Each carbon atom forms three sigma bonds in a planar arrangement.

It creating layers of hexagonally arranged carbon atoms that can slide over one another.

It contributing to graphite's lubricating properties.

Explanation

Glucose is NOT an example of amorphous solids; it is a crystalline solid.

In contrast, glass, plastic, and rubber are amorphous solids.

It lacking a well-defined crystalline structure.

Explanation

When a substance is cooled slowly, only a limited number of nucleation sites are formed.

As a result, larger crystals are produced.

The better crystals tend to be obtained on slow cooling than on rapid cooling

• because rapid cooling induces the formation of many nucleation sites
• fast cooling yields small crystals.
  

Explanation

Methane molecule is sp3 hybridized and has a perfect tetrahedral geometry

Explanation

Explanation

When a molecule has an unequal distribution of alkyl groups on either side of a functional group, metamerism occurs.

Metamerism is a type of isomerism that happens when different alkyl chains are present on either side of a functional group.

Explanation

Explanation

Ethanol gives the iodoform reaction because it contains a methyl group adjacent to the hydroxyl-bearing carbon.

It forming iodoform (CHI₃) when reacted with iodine and a base.
