The fact that you want to yes is funny
1. true

4. true
5.false
6. It's true but can be false because a change in state can be a physical change as well.

A pi bond is a bond formed by the overlap of orbitals in a side-by-side fashion with the electron density concentrated above and below the plane of the nuclei of the bonding atoms. ... Three sigma bonds are formed from each carbon atom for a total of six sigma bonds total in the molecule.
Answer:
The correct Option is C (It is polar, because the bond polarities add together in a bent molecule.)
Explanation:
The molecular structure of Hydrogen Sulfide (H₂S) is attached below;
The molecule of Hydrogen Sulfide is polar due to following two reasons;
1) Electronegativity Difference:
Sulfur has an electronegativity of 2.58 while that of Hydrogen is 2.20. Hence, sulfur being more electronegative attracts the electron fro hydrogen making it slightly partial positive and increasing electron density and becoming slightly partially positive. So, we can call this bond as slightly polar bond.
2) Dipole Moment:
Dipole moment occurs when the bond is polar. Being a vector quantity it strongly depends upon the geometry of a molecule. In H₂S the two polar bonds cannot cancel each other because they are not in opposite direction as that found in case of CO₂. Hence, H₂S is a polar compound.
