Towards the end of the year, the weather in Seville starts to become slightly milder. In October, the sun shines for at least 7 hours per day but brace yourself for rain as there are on average 6 days of rainfall during the month.
When a molecule has no dipole moment, like CO2, then it is nonpolar. When a molecule has a dipole moment like water, then it is polar. This polarity business is very important. Polar molecules are like little magnets, with a positive end and a negative end, and they interact with each other through magnetic attractions.
(g) CBr4 polar C-Br bonds, no dipole moment C Br Br Br Br Polar C-Br bonds; no net dipole moment because all dipoles cancel each other (h) CH3COCH3 polar C-O bond, dipole moment O CH3 H3C net dipole moment 4. Draw all important resonance structure for the following species. If applicable, indicate major and minor resonance contributors (a) H2C=N=N (b) O=OâO C C C C C H H H
