• from ethyne,

first you need to convert it to ethene and then ethane.

• from ethene,

first you need to convert it to ethane.

after converting to ethane, now you can use :

• acidified k2cr2o7
• Cu tube at 200°C

now by controlled or catalytic oxidation of any alkane will give you its corresponding alcohol.

thus,

now convert using the compounds and at the respective conditions.

Cu tube

2C2H6 + O2 ------------> 2C2H5OH
