Here are the answers to [[2021-2022 Honors Chem328 Polarity, IMF and Physical Properties Review HW]]<br> <br> 1) <br> <br> 2)<br> *N<sub>1</sub>H<sub>3</sub>: 8ve<sup>-</sup>, 3 single bonds, N is central atom with 1 lone pair (LP), Pyramidal (107.0°), sp<sup>3</sup> *B<sub>1</sub>F<sub>3</sub>: 24ve<sup>-</sup>, 3 single bonds, B is central atom with no LP, Trigonal planar, 120°, sp<sup>2</sup> *N<sub>2</sub>: 10ve<sup>-</sup>, 1 triple bond, no central atom, Linear (180°), NA *C<sub>1</sub>O<sub>2</sub>: 16ve<sup>-</sup>, 2 double bond, C is central atom with 0 LP, Linear (180°), sp<br> <br> 3)<br> *CCl<sub>4</sub>, ΔEN =0.5, 4 non-polar bonds, Tetrahedral (sym), NA, non-polar molecule, LDF<br> *<nowiki>BeCl</nowiki><sub>2</sub>, ΔEN =1.5, 2 polar bonds, Linear (sym), Yes, non-polar molecule, LDF *CS<sub>2</sub>, ΔEN=0.0, 2 non-polar bonds, Linear (sym), non-polar molecule, LDF *NF<sub>3</sub>, ΔEN=1.0, 3 polar bonds, Pyramidal (not sym), polar molecule, dipole-dipole<br> <br> 4) sp<sub>3</sub> hybridized<br> <br> 5)<br> <br> 6)+-->, Arrow over the more electronegative atom (or whatever way you memorize the symbol).<br> <br> 7) Ionic ΔEN> or = 1.7<br> polar bond is 1.7<ΔEN> or = 0.8<br> non-polar ΔEN<0.8<br> <br> 8) Assume polar prove non-polar<br> <br> 9) <br> <br> 10) Dipole-dipole (D - D) interaction<br> <br> 11) Yes<br> <br> 12) No, polar or non-polar is for covalent (sharing) bonds<br> <br> 13) False<br> <bR> 14) NH<sub>3</sub>, has more Hydrogen bond (actually it is H<sub>2</sub>O<sub>1</sub>)<br> <br> 15) <br> <br> 16) H<sub>2</sub>O<sub>1</sub> is a polar molecule and oil is a hydrocarbon (C<sub>x</sub>H<sub>y</sub>) a non-polar molecule. So H<sub>2</sub>O<sub>1</sub> exerts coloumbic force (CF) while oil does not. So H<sub>2</sub>O<sub>1</sub> molecules are interacting with other H<sub>2</sub>O<sub>1</sub> molecule so they will "push oil molecules" around so they will be together.<br> <br>
