00), XC (mw 80) and XD (mw 120) None of the four molecules can hydrogen bond. During the evaporation of XD, IATI 4.7°C. What would be the expected |ATI during the evaporation of XC? 4.70C 10.1°C 2.5°C 7.2°C Submit Answer Tries 0/2 6. Which statement is correct? Evaporation is an exothermic process. Only molecules Only nonpolar molecules have dispersion forces. Only polar molecules have dispersion forces. Only molecules that can hydrogen bond have dispersion forces. None of these statements are correct Sutmit Answer Tries 0/2 that cannot hydrogen bond have dispersion forces. 7. of Br2, 12, C2 and F2, which one has the strongest dispersion forces? Cl2 Br2 12 They all belong to the same family, the halogens, and have the same number of valence electrons. Because of this, the dispersion forces for all four are identical. Subrsit Ansmer Tries 0/2 8. Can two of these molecules hydrogen bond with each other? YES NO ubmi Answer Tries O/2Explanation / Answer
Question no 6
Since all the atoms have electrons, therefore they have dispersion forces to some extent.
Moreover both polar and non polar molecules can have dispersion forces. And evaporation is an endothermic reaction.
Hence all the statements are false.
Hence option (6) is correct.
Question no 7
I2 has strongest dispersion force. This is because I2 here has maximum no of electrons thereby increasing the scope for dispersion forces.
Hence option (c) is correct.
Question no 8
Hydrogen bond occurs when H is covalently attached to electronegative element but here it is attached to C which is not electronegative, hence the hydrogen bonding will not occur in this molecule.
