Consider the following substances:

I. Ethanol 

II. Nitroglycerine 

III. Urea

Coal gasification technology can be used in the production of how many of them?

Select an option to attempt

Explanation

Coal gasification produces syngas (carbon monoxide + hydrogen), which is a starting point for making many chemicals.

✅I. Ethanol – Syngas can be converted into ethanol using chemical processes. ✅II. Nitroglycerine – Though not made directly, syngas helps produce chemicals (like hydrogen and methanol) needed to make nitroglycerine. ✅III. Urea – Syngas is used to produce ammonia, a key ingredient for urea production.

All three substances can be produced using coal gasification technology.
