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 electronegativity difference makes the bond polar and it is NOT symmetrical Br-F has two distinct ends and the F end is more negative O=C=O is symmetrical and even with polar bonds it is non polar that goes for CF4 also. was told if its symmetrical its not polar. I could understand if H-H is no polar but what about Br-F or even CH3 Are they polar or non-polar. Update: Is it right I use electronegativity by saying F is more negative so the molecule is polar..but their symmetrical. Follow.
