Question

10 difference between covalent and electrovalent

Answer 1

Answer:

While she stuck to making things that were not very complicated, all her recipes were courtesy of Tanya.

On the cusp of the coronavirus pandemic, in January this year, Tanya decided to go back to Jammu. Having spent two years in Delhi, she began feeling homesick and thought that moving back home was perhaps a “very wise decision”. While the move offered her comfort, her passion for cooking kept prompting her to find ways to get back into the kitchen.

“I was never interested in academics but even though I did not know what I wanted to do, I was always clear on what I wanted to stay away from,” says Tanya, adding, “Managing to convert a passion into a career has been rather fulfilling.”

Answer 2

Answer:

• 1) Electrovalent compounds- These compounds are formed by transfer of electrons between atoms.
• Can conduct electricity in molten or solution state.
• Have high melting and boiling point.
• They contain metal atoms in their molecules
• Ions are involved in the bond formation.
• Soluble in polar solvents like water.
• Insoluble in nonpolar solvents like benzene or carbon tetrachloride.
• Hard, crystalline solids.
• Formed as a result of the large difference in electronegativity of atoms.
• They are frequently inorganic compounds.

• 2) Covalent compounds- These compounds are formed by mutual sharing of electron pairs between atoms.
• Cannot conduct electricity.
• Have low melting and boiling point.
• They do not contain metal atoms in their molecules.
• Atoms are involved in the bond formation.
• Insoluble in polar solvents like water.
• Soluble in nonpolar solvents like benzene and carbon tetrachloride.
• Usually liquids or gases.
• Formed as a result of small difference in electronegativity of atoms.
• They are frequently organic compounds.
