Explanation

Acetylene has a triple bond between two adjacent carbon atom 

And the bond length is even shorter. 

it is closer to 120 pm

Each carbon atom in a diamond is surrounded by 4 other carbon atoms.

And connected to them by a strong single covalent bond- the strongest type of chemical bond.

The bond length is 154 pm.

Hence the shortest C - Bond distance is found in acetylene which is 120 pm.

Additional information:

Note that as the C-C bond length is shortening, the bond length of C-H is alose decreasing.

This is due to the presence of hyperconjugation in alkene and alyknes 

Where each bond attains a partial double bond character.

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

The reasoning in which the given statements are viewed as supplying strong evidence for the truth of the conclusion is called inductive reasoning.

Inductive reasoning is applied in this context:

1. Observations (Given Statements): 

2. Generalization (Conclusion): 

3. Strength of Evidence:

5. Application in Everyday Reasoning:
