2)अस्थिर असतात / Volatile
3)मिश्र रसायनांची असतात / Made up of complex chemicals
4)वंगणासारखी असतात / Greasy✓ Correct

Vegetable oils are generally triglycerides of unsaturated fatty acids, characterized by carbon-carbon double bonds and liquid state at room temperature.

__________ हे तेल आणि चरबीमधले असंतृप्तता मोजण्यासाठी वापरतात. __________ is used to estimate the presence of unsaturation in oils and fats.

1)साबणीकरण मूल्य / Saponification value
2)आयोडिन मूल्य / Iodine value✓ Correct
3)आम्ल मूल्य / Acid value
4)विष्पदिता मूल्य / Viscosity value
