उत्तर : 4. "All the above"
व्याख्या :
Answer: D) All the above Explanation: 1) SO2 2) CH2Cl2 3) PCl3 How to check the given molecules are polar or non polar : If the electronegativity of the two bonded atoms are different then the bond is polar. Although, some molecules contain polar bonds, the molecule may be non-polar. If the polarity of all the bonds present in the molecule are cancel each other then molecule is non-polar. In the given options, SO2 is polar because the dipole moments on the O do not cancel. PCl3 is polar because the P-Cl bonds do not cancel out. CH2Cl2 polar because the C-Cl bonds do not cancel. Hence, in brief, Polar molecules are molecules with net dipole due to the presence of partial positive and partial negative charge. For example, water is a polar molecule that has partial positive and partial negative charge on it. CO2 is a non polar compound. Therefore, all the given options SO2, CH2Cl2 and PCl3 are Polar molecules.

उत्तर : 3. "18.5"
व्याख्या :
Answer: C) 18.5 Explanation: The given series pattern follows 17 9 10 18.5 35 90 × 0.5 + 0.5, × 1 + 1, × 1.5 + 1.5, × 2 + 2, × 2.5 + 2.5 So here 17x0.5 + 0.5 = 9 9x1 + 1 = 10 10x1.5 + 1.5 = 16.5 16.5x2 + 2 = 35 35x2.5 + 2.5 = 90 Here the odd man in the given series is 18.5
