The compound formed between two non-metals will be expected to Abe a solid Bhave a high melting pointCbe acidic Dbe covalent

Break Down the Problem

1. Identify the characteristics of compounds formed between non-metals.
2. Analyze each option to determine its validity regarding non-metal compounds.

Relevant Concepts

• Non-metallic compounds often exhibit certain properties including molecular composition, state of matter, melting points, and acidity.
• Covalent bonding is a key feature of compounds formed between non-metals.

Analysis and Detail

1. Option A: Be a solid

   • Many non-metal compounds can exist in various states (solid, liquid, gas) at room temperature. Therefore, this statement is not universally true.

2. Option B: Have a high melting point

   • Non-metal compounds typically have lower melting points compared to ionic compounds. Thus, this statement does not hold true for all non-metal compounds.

3. Option C: Be acidic

   • Some non-metal compounds can be acidic (e.g., HCl), but not all non-metal compounds are acidic. Hence, this is not always applicable.

4. Option D: Be covalent

   • Compounds formed between non-metals are primarily covalent due to the sharing of electrons between the atoms. This is a defining characteristic of non-metallic compounds.

Verify and Summarize

After analyzing each option, it is evident that while some may be true in specific cases, the most universally valid statement about compounds formed between non-metals is that they are covalent.

Final Answer

The correct answer is D: be covalent.
