Question

3) Consider the Lewis structure for CH3COH shown below. Draw polar bonds as arrows instead of the lines, and determine whether the molecule is polar overall. 

4) Draw in the polar bonds on the Lewis diagrams below. Are CH3OH and H20 polar or non-polar overall? Are they miscible or immiscible? 

5) Draw in the polar bonds on the Lewis diagrams below. Determine if each substance is polar or non-polar overall, then whether a homogeneous or heterogeneous solution forms when the substances are mixed.

Answer 1

3) consider the lewis Draw polar bonds and determine whether structure for choon shown below. as arrows instead of the lines, the molecule is polar overall. b: In -->0: 4- > и overall dipole moment & > Arrow indicate polar bond or transfer of é in covalent bond since molecule hat net non zero dipole moment so molecule is polar. - 4 Draw Are Are in the polar bonds on the cnzon and H₂O polar or they miscible or immiscible ? lewis diagram below non polar over all ? S- > S- Polar bond : HC St direction \ St / of overale dipole moment direction of overall dipole moment Since both choon and H₂O have net non zero dipole moment. so both chaon and H₂O are polar molecule since both chzon and H₂O have dipole moment so both are permanent dipole and have dipole - dipole van der wal force of attraction so 68th are miscible

Draw in the polar bands on the below. Determine if each substance non polar overall. Then whether a heterogeneous solution forms when the lewis diagram is polar or homageneous or substance are mixed. c Bry H₂O 一个c/ st polar - bond In this care on bond is polar bond and also overall molecule is also polar in this care c-Br bond is polar bond as shown in diagram but overall molecule is a non-polar molecule. This is because all 4 Br are at tetrahedral corner and dipole moment of each bond is concel out by other three bonds and overall dipole moment of ebru is zero and it is a non polar molecule When both heterogeneous non polar. heterogeneom Bru and solution so both solution H₂O mixed became one are immcible they is polar and other form and form

Answer 3

Hé!! Electronegativity difference CH¢-cro in C-H bond is very dess because ENC - ENA = 2:5-21 = 0.4 is less than 0.5 C-H bond is non polar. Ro. co. bond ENC - E.NO = 2.5 - 3.4 = - (=o bond is pelar . For Ort boud. ENO ENM= 3.4-2. 1.3 OrH bond is also polar u so, CM COOH v polar Harçrero presö se OrH bond to bond is al and ekoh is a polar molecule H o IT because oth boud is polar no is a polar moleciile as in the shape of molecule is nott linear and the polarity is not cancelled out a
