Question

Identify the compound X on the basis of the reactions given below.

Answer 1

Explanation:

Given -

1. Compound X + Zn → A + H2 (g)
2. Compound X + HCl → B + H2O
3. Compound X + CH3COOH → C + H2O

To Find -

• What's compound X ?

Solution -

Here, we see that compound X on reaction with HCl form compound B and realeses water.

For releasing water H+ OH- ion formation is necessary.

HCl gives H+ . Now, we need OH- to form water. It means, Compound X gives OH- . It means, Compound X is alcohol.

Now,

Compound X is alcohol. On treating alcohol with Ethanoic acid (Carboxylic acid) then it forms Ester.

And we know that, C2H5OH reacts with CH3COOH to form Ethyl ethanotate (Ester) and water.

Now, It's cleared that Compound X is C2H5OH.

1)

Compound X + Zn → A + H2 (g)

It means,

C2H5OH + Zn → C2H5OZn + H2

2)

Compound X + HCl → B + H2O

It means,

C2H5OH + HCl → C2H5Cl + H2O

3)

Compound X + CH3COOH → C + H2O

It means,

C2H5OH + CH3COOH → CH3COOC2H5 + H2O

Hence,

Compound X is Ethanol (C2H5OH).
