Halide of an element when heated with LiAlH4 to give compound (B). Compound (B) reacts with H2O to give compound (C) which is antiseptic. Find A B & C. Write down structure of compound (B).

Answer:

E is B (Boron).

A: BHal₃

$$4 \mathrm {B H a l} _ {3} + 3 \mathrm {L i A l H} _ {4} \rightarrow 4 \mathrm {B H} _ {3} + 3 \mathrm {L i H a l} + 3 \mathrm {A l H a l} _ {3}$$

B: BH₃

$$B H _ {3} + 3 H _ {2} O \rightarrow B (O H) _ {3} + 3 H _ {2}$$

C: $\mathrm{B}(\mathrm{OH})_3$
