Question

1 example which has additive as well as constitutive property

Answer 1

Answer:

Additive and Constitutive Properties: The physical property which depend upon the number of atom in a molecule as well as their constitution, is known as additive and constitutive properties. e.g., atomic volume, parachor etc.

Answer 2

Polarity of a compound is an example of both additive and constitutive property.

• Additive property can be defined as the one which is obtained from the sum of the individual component values in a substance. For example, the molecular weight of a compound is the sum of the atomic mass of all the atoms in it and does not depend on how those atoms are arranged.
• Constitutive property is the one that is dependent on the arrangement or positioning of the individual components in an entity. Optical activity is an example of constitutive property.
• An additive and constitutive property is the one that is basically an additive property but is also dependent on the positioning of the individual components. An example is the polarity of a molecule, which is the sum of dipole moments of all the individual bonds and is dependent on the direction of bonds.
