Question

Which alcohol is not soluble in water? Select the correct answer below:

methanol

ethanol

1-hexanol

2-propanol

Which among these is not liquid at room temperature? Select the correct answer below: ethanol

butanol

methanol

hexanol

Answer 1

1) 1-hexanol

In the given alcohols, 1-hexanol is not soluble in water. This is because it has cyclohexyl group as a more hydrophobic group while other alcohols have lesser hydrophobic groups.

2) butanol

The melting point of tertiary butanol is 25-26°C. Therefore, this compound is solid at 20-25°C (Room temperature). Thus, among these, tertiary butanol is not liquid at room temperature.
