Question

which of the following pair will produce same gaseous product with h2o? also give the reaction for confirmation ​

Answer 1

Answer:

options 1st

I hope it is helpful to you

Answer 2

Option 2) Aluminium Carbide and Beryllium Carbide form same gas when it reacts with water.

Hydrolysis of Carbides

We have to find the products when the given carbides undergoes hydrolysis reactions.

• When Calcium carbide undergo hydrolysis it forms Calcium hydroxide and Ethyne gas.

$H_2O + CaC_2 --- > Ca(OH)_2 + C_2H_2(gas)$

• When Aluminium carbide undergo hydrolysis it forms Aluminium hydroxide and methane gas.

$Al_4C_3 + 12 H_2O ---- > 4 Al(OH)_3 + 3 CH_4 (gas)$

• When Beryllium carbide undergo hydrolysis it forms Beryllium hydroxide and methane gas.

$Be_2C + H_2O ---- > Be(OH)_2 + CH_4(gas)$

• When Magnesium carbide undergo hydrolysis it forms Magnesium hydroxide and propyne gas.

$Mg_2C_3+4H_2O---- > Mg(OH)_2+C_3H_4 (gas)$

• Therefore Aluminium and Beryllium carbides produces same methane gas on hydrolysis.

Thus option 2) is the correct answer.
