(i) \(\text { Boron }+\mathrm{O}_{2} \xrightarrow{700^{\circ} \mathrm{C}}(\mathrm{X})\)
(ii) \((\mathrm{X})+\mathrm{C}(\text { carbon })+\mathrm{Cl}_{2} \rightarrow(\mathrm{Y})+\mathrm{CO}\)
(iii) \((\mathrm{Y})+\mathrm{LiAlH}_{4} \rightarrow(\mathrm{Z})+\mathrm{LiCl}+\mathrm{AlCl}_{3}\)
(iv) \((\mathrm{Z})+\mathrm{NH}_{3} \rightarrow(\mathrm{~A}) \xrightarrow{\text { Heat }}(\mathrm{B})\)
(v) \((\mathrm{Z})+\mathrm{NaH} \rightarrow(\mathrm{D})\)
Compounds (X) and (Y) are:

(X) = BO₂, (Y) = BCl₂
(X) = BO₃, (Y) = BCl₄
(X) = B₂O₃, (Y) = BCl₃
(X) = BO₃, (Y) = B₄C

Answer

(C) (X) = B 2 O 3 , (Y) = BCl 3
