Compare Electrovalent (Ionic) and Covalent compounds. Solution: | Property | Electrovalent Compounds | Covalent Compounds | | :--- | :--- | :--- | | State | Usually solid, hard, and brittle | Usually liquids or gases (or soft solids) | | Solubility | Soluble in water, insoluble in organic solvents | Insoluble in water, soluble in organic solvents | | Conductivity | Conduct electricity in molten or aqueous state | Do not conduct electricity | | Melting Point | High | Low |
The Viraf J. Dalal solutions are widely considered the "Gold Standard" for ICSE Class 10 Chemistry preparation. Unlike standard textbooks that only provide answers, these solutions are structured to teach the method of writing answers that ICSE examiners look for. For a student aiming for a high distinction (90%+), this book is almost mandatory.
