Question

C2 h6 c2 h4 c2h5oh ch3 coh ch3 cool

Answer 1

C2H6 (t, Ni)= C2H4 + H2

C2H4 + HOH (H2SO4(k)) = C2H5OH

C2H5OH + CuO (t)= CH3COH + Cu + HOH

CH3COH + Ag2O (t)= CH3COOH + 2Ag

Answer 2

It looks like you've provided a series of chemical formulas and names. Let me identify each one for you:

1. C2H6: Ethane
2. C2H4: Ethene (or ethylene)
3. C2H5OH: Ethanol
4. CH3COH: Acetone
5. CH3COCH3: Acetone (it's the same as the previous one; it's a common abbreviation)
6. CH3COOH: Acetic acid (also known as ethanoic acid)

These are organic compounds commonly encountered in chemistry and everyday life. If you have any specific questions about these compounds or their properties, feel free to ask!
