Melting Point // Takat lebur : -114 ° C

Boiling Point // Takat didih : 78.3 °C

Why does ethanol have a high boiling point compared to its melting point?

Mengapakah ethanol mempunyai takat didih yang tinggi berbanding takat leburnya?

Because ethanol has strong ionic bonds

Kerana ethanol mempunyai ikatan ion yang kuat

Because ethanol is an intoxicating alcohol

Kerana ethanol adalah alkohol yang memabukkan

Because ethanol has a strong metal bond

Kerana ethanol mempunyai ikatan logam yang kuat

Because there are hydrogen bonds formed between ethanol molecules

Kerana terdapat ikatan hidrogen terbentuk antara molekul- molekul ethanol
