Question

3. (3 pts) Hydrazine (H2NNH2) and hydrogen peroxide (HOOH) have exceptionally high surface tensions compared with other substances of similar molecular weights. Draw the Lewis structures for these two compounds - the formulae are written to show the connectivity of the atoms. Use the structures to determine the intermolecular forces present, and provide an explanation for the high surface tensions.

Answer 1

Answer is briefly explained in the attachment,

Hydrazine ( L EH TEH dobili :NN: Or H 4 Hydrogen peroxide 1 As in both ® ¢ ® are quite polar molecule. In ③ hydrogen ends being positive & Oxygen ends being extremely negative, while in ③ hydrogen ends being positive & ninogen ends being negative. Several intermolecular Porces can occur when molecule bonds with itself. 2) These forces are London dispersion , dipole-diapole bonds 4 Hydrogen bonding. Due to these attractive molecular forces acting across the layer of liquids maker A B more viscous than other in ct similar mokcular. Wt. han brother molecule
