Question

A+C(carbon)Δ−−−−−High tempB+G(gas)G(gas)+O2−−−−−−−−−−−−Burn with blue flameD(gas)B+H2OF+H(gas)
A+H2OF
F+D(gas) milky solution, Milky solution disappears if more gas D is passed
B+N2ΔJ+Carbon

List-I contains questions related to information given above and List-II contains their answer(s) as compounds from above information.
List - IList - II(I)Which oxygen containing compound(s) is/are(P) Jbasic in nature?(II) Which compound(s) on hydrolysis can give urea?(Q) B(III) Which compound(s) has/have triple bond or(R) Fbond order equal to 3 but not contain(s) nitrogen?(IV) Which gas(es) on combustion give(s) D(S) A(T) G(U) H

Which of the following options has the correct combination considering Lists-I, II?
  1. (I), (S) and (II), (U)
  2. (I), (R) (S) and (II), (P)
  3. (I), (R) (S) (T) and (II), (P)
  4. (I), (Q) (R) (S) (U) and (II), (U)


Solution

The correct option is B (I), (R) (S) and (II), (P)
Since F+Dmilky solution, So D(gas)=CO2
and F=Ca(OH)2.
Given, A+H2OCa(OH)2
 Thus, A=CaO
Again, CaO+carbonΔB+G(gas)
B=CaC2
Also, G (gas) burns with blue flame. So, it is CO
Given, CaC2+N2ΔJ+Carbon
J=CaCN2
CaC2+H2OCa(OH)2+H(gas)
H(gas)=C2H2
So, we have,
CaO and Ca(OH)2 as oxygen containing compounds which are basic in nature 
Ca(CN)2 on reaction with water gives urea.
