|
The molecule has tendency to absorb a lot of heat, therefore it remains ‘cold’ easily
|
|
|
The molecule has an even distribution of charges, all parts are positive
|
|
|
The molecule has an even distribution of charges, all parts are negative
|
|
|
The molecule has an uneven distribution of charges, some parts are positive while others are negative

Detailed explanation-1: -The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
Detailed explanation-2: -A molecule with an unequal distribution of charge, which results in the molecule having a positive end and a negative end is called a polar molecule. Molecules are polar when their atoms have different levels of electronegativity, or affinity for electrons.
Detailed explanation-3: -A polar molecule is a type of molecule that has a separation of electric charge, where one side of the molecule is positively charge and the other side is negatively charged.
Detailed explanation-4: -A polar bond is a type of covalent bond. A bond between two or more atoms is polar if the atoms have significantly different electronegativities (>0.4). Polar bonds do not share electrons equally, meaning the negative charge from the electrons is not evenly distributed in the molecule. This causes a dipole moment.
Detailed explanation-5: -When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don’t, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).
