I've found conflicting answers on the internet so I wanted to ask here. I was always taught throughout high school that covalent bonds are stronger than ionic bonds. But I came across a question in the textbook asking which of two substances would have a higher boiling point and I know that it has to be the one with the stronger bond. One of them is covalent HCl and the other is ionic NaCl. I googled which was stronger and I found some people saying ionic is stronger and some people saying covalent is stronger. And now i'm just confused.
It depends on the situation. In biology you hear that covalent bonds are stronger because you are usually comparing covalent bonds with ionic bonds in water. When ionic bonds are in water they are much weaker. However, in chemistry you usually say that ionic bonds are stronger because they are harder and take more energy to break than covalent bonds when they are not dissolved in a solution.

so then should we always assume that salts are stronger than covalent bonds? does that change when they are in aq solution?
