Q1. Write a brief note on the preparation, structure, and bonding of diborane (B₂H₆). (6 marks)

Answer:
Diborane can be prepared by reducing boron trifluoride (BF₃) with lithium aluminium hydride or by reacting sodium borohydride (NaBH₄) with acids. The molecule consists of two boron atoms linked to four terminal hydrogen atoms and two bridging hydrogen atoms. The four terminal B–H bonds are normal covalent bonds, while the two bridging hydrogen atoms form three-centre two-electron bonds,

2. Features of Classroom Discussion

Classroom discussion is an interactive technique that promotes student thinking, participation, and collaborative learning. One of its major features is active involvement of learners.

Another key feature is exchange of viewpoints. Students listen to multiple perspectives and learn

A Python dictionary is a collection of key-value pairs used to store data in an unordered, mutable structure. You create a dictionary using curly braces `{}` with key-value pairs, for example: `my_dict = {"name": "Alice", "age": 25}`. You can also use the `dict()` constructor to create dictionaries. Accessing values is done by referring to their keys: `my_dict["name"]` returns `"Alice"`. 

You add or update items by assigning a value to a key, such as `my_dict["city"] = "New York"` to add new or

1.Saliva: Lubricates food for swallowing, moistens the mouth, and contains the enzyme Salivary Amylase (Ptyalin) which begins the digestion of carbohydrates (starches).HCl (Hydrochloric Acid): Maintains an acidic pH (1.5–3.5) in the stomach to activate pepsinogen into pepsin (for protein digestion) and kills ingested bacteria/microbes.
