Mode of attachment of ligand to metal atom gives rise to ......isomerism.

Explanation

To solve the question, we need to fill in the blank in the sentence: "Mode of attachment of ligand to metal atom gives rise to ______ isomerism."

### Step-by-Step Solution:

1. **Understanding the Context**: The question is asking about a specific type of isomerism that arises due to the way ligands attach to a metal atom in coordination compounds.

2. **Identifying Key Terms**: From the video transcript, we learn that the mode of attachment of ligands can lead to different types of isomerism. The term "linkage isomerism" is specifically mentioned as a type that arises from the attachment of ligands.
