Question

alcohol is a liquid. justify!

Answer 1

Alcohols all contain the OH-group, with the oxygen being partially negatively charged and the hydrogen being partially positively charged. Inside the liquid (as well as in the solid/gas) phase, the positive hydrogen interact with negatively charged oxygen on neighbouring molecules. This interaction is attractive and thus helps hold the liquid together and is commonly referred to as a hydrogen bond.
And hence justified!

Answer 2

Liquid has a property that its intermolecular space is more better than gases and less than that of solid.

Liquid burns with a blue or clear flame.

Volume of liquid is fixed but its shape is not fixed.

Less intermolecular attraction than solid and more than gases.

We can stir liquids.

And all these things are with Alcohol.

So, it proves that alcohol is a liquid.
