When a substance '

A

' reacts with water, it produces a combustible gas '

{B}

' and a solution of substance '

{C}

' in water. while another substance '

D

' reacts with solution of

'C'

to produce the same gas

'B'

on warming while '

{D}

' can produce gas '

{B}

' on reaction with dilute

{H}_2 {SO}_4

at room temperature. '

A

' imparts a deep golden yellow colour to a smokeless flame on Bunsen burner. Identify

'A', 'B', 'C'

and '

{D}

' respectively are

View answer and explanation

Correct option: B

{Na}, {H}_2, {NaOH}, {Zn}

Option B (

{Na}, {H}_2, {NaOH}, {Zn}

) is correct because sodium reacts with water to produce hydrogen gas and sodium hydroxide, and zinc reacts with sodium hydroxide to produce hydrogen gas.
