Question

Match the List-I with List-II

	List-I (Reactions of Boron at certain condition)		List-II (Products)
(P)	Boron on reaction with metals		(1) Borates
(Q)	Boron on reaction with acids		(2) Boric acid
(R)	Boron on reaction with alkalles		(3) Borides
(S)	Boron on reaction with Nitrogen		(4) Boron nitride
			(5) Boron sesquioxide

Choose the correct answer from the options given below.

• A. P–1, Q–2, R–3, S–4
• B. P–3, Q–2, R–1, S–4
• C. P–2, Q–3, R–4, S–5
• D. P–3, Q–4, R–5, S–1

Answer 1

Answer: (B)

P–3, Q–2, R–1, S–4

Answer 2

• Reaction with Metals (P): Boron reacts with metals to form borides.
  ⇒ (P) → (3) Borides

• Reaction with Acids (Q): Boron reacts with acids to form boric acid.
  ⇒ (Q) → (2) Boric acid

• Reaction with Alkalis (R): Boron reacts with alkalis to form borates.
  ⇒ (R) → (1) Borates

• Reaction with Nitrogen (S): Boron reacts with nitrogen to form boron nitride.
  ⇒ (S) → (4) Boron nitride

Thus, the correct matching is:
P–3, Q–2, R–1, S–4
