Causes of Retinal Hemorrhage. In adults, the causes of retinal hemorrhages are quite common and easy to understand. A forceful blow to the head can result in a retinal hemorrhage. Those who have been in an accident, been assaulted or have taken a fall in which they hit their head may experience a retinal hemorrhage.
Carbon monoxide is polar because oxygen is more electronegative than carbon giving oxygen a partila negative charge and carbon a partial positive charge. There is a net dipole moment.n the free carbon monoxide, a net negative charge Î´- remains at the carbon end and the molecule has a small dipole moment of 0.122 D The molecule is therefore asymmetric: oxygen has more electron density than carbon, and is also slightly positively charged compared to carbon being negative.
The molecular property that determines which type of intermolecular bond can exist between two molecules is called polarity. A polar molecule is one in which one side of the molecule is slightly positively charged and the opposite side is slightly negatively charged.s a result, C-H and Cl-N bonds are almost completely non-polar. Bonds between carbon and chlorine, carbon and bromine, and carbon and iodine are also only very slightly polar. But electrons are in constant motion, and there are brief periods of time in which they are slightly to one side of the molecule or the other.
