Answer 1

Answer:

a is correct

Explanation:

hope its help you dearr

Answer 2

Answer:

A) c > a = b

Explanation:

• Dipole moment of p – dichlorobenzene is zero due to symmetrical structure.
• Para-dinitrobenzene has a zero dipole moment
• Net dipole moment of p-dimethoxybenzene is not zero because it exist in two different form i.e. cis and trans forms. So, we have to take the average value of both their dipole moments.
