Which of following is a polar molecule 1) KCl 2) F – F (3) H-O-H (4) S8<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer: (3) H\u2013O\u2013H<\/strong><\/p>\n\n\n\n A polar molecule is one that has a net dipole moment due to unequal sharing of electrons between atoms with different electronegativities and an asymmetric molecular shape.<\/p>\n\n\n\n H\u2013O\u2013H (Water)<\/strong> is a polar molecule. Oxygen is much more electronegative than hydrogen, which causes the electrons in the O\u2013H bonds to be pulled closer to the oxygen atom. Additionally, water has a bent molecular geometry with an angle of about 104.5\u00b0, not a straight line. This asymmetry ensures that the dipoles from the two O\u2013H bonds do not cancel out, giving the molecule an overall dipole moment. Therefore, water is a classic example of a polar molecule.<\/p>\n\n\n\n KCl (Potassium Chloride)<\/strong> is not a polar molecule; it is an ionic compound<\/strong>. It consists of a metal (potassium) and a non-metal (chlorine). Electrons are transferred, not shared, between the atoms, resulting in full positive and negative charges. Although the bond is highly polar, the compound as a whole is not considered a polar molecule because it forms a lattice structure typical of salts.<\/p>\n\n\n\n F\u2013F (Fluorine gas)<\/strong> is a nonpolar molecule. It consists of two identical fluorine atoms sharing electrons equally. Because there is no difference in electronegativity, there is no dipole moment, and the molecule is completely nonpolar.<\/p>\n\n\n\n S\u2088 (Sulfur octamer)<\/strong> is also nonpolar. It has a symmetrical ring structure made up of identical sulfur atoms. The electrons are shared equally, and the molecule has no net dipole moment.<\/p>\n\n\n\n In conclusion, among the given options, only H\u2013O\u2013H meets the requirements for being a polar molecule due to its bond polarity and molecular geometry. It has an uneven charge distribution, making it polar.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of following is a polar molecule 1) KCl 2) F – F (3) H-O-H (4) S8 The correct answer and explanation is: Correct Answer: (3) H\u2013O\u2013H A polar molecule is one that has a net dipole moment due to unequal sharing of electrons between atoms with different electronegativities and an asymmetric molecular shape.
