When an inorganic compound `(X)` having `(3c, 2e)` as well as `(2c, 2e)` bonds reacts with ammonia gas at a certain temperature and gives a compound `(Y)`. Which is isostructural with benzene. Compound `(X)` with ammonia at very high temperature gives `(Z)` also known as inorganic graphite. Identify `(X),(Y)` and `(Z)`.

A

X is `BH_(3)`, Y is `B_(2)N_(2)H_(3) and Z` is inorganic benzene

B

X is `B_(2)H_(6)`, Y is `B_(3)N_(3)H_(6)` And Z is boron nitride

C

X is borax Y is `B_(2)O_(3)`, Z is inorganic benzene

D

X is `BH_3 `, Y is `B_(2)O_(3)` and Z is inorganic benzene

The correct Answer is:
To solve the problem, we need to identify the compounds \(X\), \(Y\), and \(Z\) based on the information given about their bonding and reactions. ### Step-by-Step Solution: 1. **Identify Compound \(X\)**: - The question states that compound \(X\) has both 3-center 2-electron (3c, 2e) bonds and 2-center 2-electron (2c, 2e) bonds. - A well-known compound that fits this description is **Diborane (\(B_2H_6\))**. In diborane, there are 3c, 2e bonds formed between boron and hydrogen atoms. **Hint**: Look for compounds that contain boron and have unusual bonding characteristics. 2. **Reaction of \(X\) with Ammonia**: - When diborane (\(B_2H_6\)) reacts with ammonia (\(NH_3\)) at a certain temperature, it forms a compound that is isostructural with benzene. - The product formed is called **Boron Nitride (\(B_3N_3H_6\))**, which is often referred to as inorganic benzene due to its similar structure to benzene. **Hint**: Consider how ammonia can interact with boron compounds and look for products that mimic the structure of benzene. 3. **High-Temperature Reaction of \(X\) with Ammonia**: - When diborane (\(B_2H_6\)) reacts with ammonia at very high temperatures, it forms a compound known as **Boron Nitride (BN)**, which is also referred to as inorganic graphite due to its layered structure similar to graphite. **Hint**: Think about how temperature can affect the reactivity of compounds and lead to the formation of different structures. ### Summary of Compounds: - \(X = B_2H_6\) (Diborane) - \(Y = B_3N_3H_6\) (Inorganic Benzene or Boron Nitride) - \(Z = BN\) (Inorganic Graphite) ### Final Answer: - \(X\) is Diborane (\(B_2H_6\)) - \(Y\) is Inorganic Benzene (\(B_3N_3H_6\)) - \(Z\) is Boron Nitride (BN)
