What causes the different season on earth
viktelen [127]

The Short Answer: Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.

Can a molecule have bond dipoles but not have a molecular dipole?
MissTica

Answer: Yes

Explanation: A molecule has a bond dipole but not have a molecular dipole.

Dipole moment:  dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.  

Example:  

lets take an example of  CO_{2} molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and  partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.

due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.

Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.

Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.
