Of the following compounds, which would you expect to be the hardest at room temperature? srcl2 c2h6 h2o cl2

Option (a) is the correct answer.

Explanation:

Strontium chloride () is an ionic compound. And, as it is ionic in nature so there will be strong force of attraction between the two oppositely charged ions that is, and .

At room temperature, exists in solid state.

Whereas ethane () at room temperature exists as a gas.

Chemical formula of water is and at room temperature it exists in liquid state.

is a dichlorine molecule and it exists as a gas at room temperature.

Thus, we can conclude that out of the given options would you expect to be the hardest at room temperature.

the answer is a and have a great day
