Which of the following is an example of an ionic compound?
Glucose
Sugar
Table salt
Turmeric
Table salt
Table salt, chemically known as sodium chloride (Na┬аCl), is an ionic compound. It consists of a lattice of positively charged sodium ions (Na+) and negatively charged chloride ions (ClтИТ) held together by strong electrostatic forces of attraction.

Think of an ionic bond as a 'gift' exchange: one partner gives away their spare electron permanently to the other, and the two partners are then 'stuck' together because they are now electrically attracted like the north and south poles of magnets.
METAL (gives electron) + NON-METAL (takes electron) = IONIC BOND.

Ionic bonds are formed through the complete transfer of one or more electrons from a metal atom to a non-metal atom. In Na┬аCl, the sodium atom (Na, atomic number 11) loses one valence electron to form a stable Na+ cation, while the chlorine atom (Cl, atomic number 17) gains that electron to form a stable ClтИТ anion. The resulting electrostatic attraction between these oppositely charged ions creates a rigid, crystalline ionic structure.
Ionic compounds are typically solids at room temperature with high melting points.
They are formed between metals (electropositive) and non-metals (electronegative).
Glucose and sugar (sucrose) are covalent compounds, which share electrons.
Turmeric is a complex mixture of organic compounds, not a simple ionic salt.
High thermal stability due to strong lattice energy.
Good conductors of electricity when dissolved in water or molten.
They do not conduct electricity in solid form because ions are fixed in a lattice.
Essential dietary mineral for human health.
Used in food preservation and manufacturing industries.
Glucose (C6тАЛH12тАЛO6тАЛ) and Sugar (C12тАЛH22тАЛO11тАЛ) are covalent compounds containing carbon, hydrogen, and oxygen.
Option A (Glucose) and Option B (Sugar) are organic molecules held by covalent bonds.
Option D (Turmeric) contains curcumin and other biological compounds, not ionic salts.
C is correct тАФ Table salt (sodium chloride) is a classic example of an ionic compound held together by strong electrostatic forces between Na+ and ClтИТ ions.
In exams, look for Metal + Non-metal combinations to identify ionic compounds; remember that Carbon-based organic molecules are almost always covalent.
