Question

Match the compounds listed in Column I with characteristic listed in Column II

	Column I		Column II
(1)	$\left(BeO\right)_{\left(\right. s \left.\right)}$	(p)	Amphoteric in nature
(2)	$NaHCO_{3}$ (crystalline)	(q)	Imparts characteristic colour to Bunsen Flame
(3)	$BeCl_{2}$	(r)	Produce $H_{2}O_{2}$ and $O_{2}$ on reaction with $H_{2}O$
(4)	$CsO_{2}$	(s)	Shows H-bonding
		(t)	Have a chain structure

• A. (1)-p, r; (2)-p, q, t; (3)-t; (4)-q, r
• B. (1)-p; r; (2)-p, s, t; (3)-t; (4)-q
• C. (1)-p; (2)-p, q, s, t; (3)-t; (4)-q, r
• D. (1)-p; (2)-p, s, t; (3)-t; (4)-q

Answer 1

Answer: (C)

(1) $\text{BeO(s)}$ Amphoteric in nature
(2) $NaHCO_{3}$ (crystalline) Amphoteric in nature, Imparts characteristic colour to Bunsen Flame,
Shows H-bonding and Have a chain structure
(3) $BeCl_{2}$ Have a chain structure
(4) $CsO_{2}$ Imparts characteristic colour to Bunsen Flame and Produces $H_{2}O_{2}$ and $O_{2}$ on reaction with $H_{2}O$
