Q1. What is polarity and how it effect the molecules
Ans. 
Polarity refers to the separation of electric charge within a molecule, which affects its chemical properties.
• Polarity is determined by the difference in electronegativity between atoms in a molecule.

• Polar molecules have a positive and negative end, while nonpolar molecules have an even distribution of charge.

• Polarity influences various properties of molecules, such as solubility, boiling point, and intermolecular forc...read more

Q3. Chiral compound and its characteristics
Ans. 
Chiral compounds are molecules that have a non-superimposable mirror image.
• Chiral compounds have an asymmetric carbon atom, also known as a chiral center.

• They exist in two enantiomeric forms, which are mirror images of each other.

• Chiral compounds exhibit optical activity, meaning they rotate the plane of polarized light.

• They have different physical and chemical properties from their mirror images.

• Examples of chiral com...read more
