Question

Match the following. Column-1 Reaction Column-2 Main product A SO 3 ⟶ heavy water I C 2 D 2 B CaC 2 ⟶ heavy water ( excess ) II CD 4 C Al 4 C 3 ⟶ heavy water ( large excess ) III D 2 SO 3 IV C 2 D 4 V D 2 SO 4 The correct match is, A B C III I IV, A B C III IV II, A B C V I II, A B C V I IV

SO 3 ⟶ D 2 O D 2 SO 4 Same as SO 3 ⟶ H 2 O H 2 SO 4 CaC 2 ⟶ D 2 O ( excess ) Ca ( OD ) 2 + D 2 C 2 Same as CaC 2 ⟶ H 2 O ( excess ) Ca ( OH ) 2 + H 2 C 2 Al 4 C 3 + 12 D 2 O ⟶ ( large excess ) 4 Al ( OD ) 3 + 3 CD 4 Same as Al 4 C 3 + 12 H 2 O ⟶ ( large excess ) 4 Al ( OH ) 3 + 3 CH 4

	Column-1 Reaction		Column-2 Main product
A	${SO}_{3} \overset{heavy water}{⟶}$	I	$C_{2} D_{2}$
B	${CaC}_{2} \overset{heavy water (excess)}{⟶}$	II	${CD}_{4}$
C	${Al}_{4} C_{3} \overset{heavy water (large excess)}{⟶}$	III	$D_{2} {SO}_{3}$
		IV	$C_{2} D_{4}$
		V	$D_{2} {SO}_{4}$
