Unequal sharing results when there is significant difference in electronegativities. The more electronegative atom(s) draws bond electrons closer, leaving the less electronegaâ¦tive atom(s) slighty positive. The result of unequal sharing of electrons is the formation of polar bonds.

By 1831 cholera had arrived in Hamburg, and the first case in England was reported in October 1831 in Sunderland. The first case in East London was on 12 February, 1832.For all the fear attached to this new disease, only about 800 persons died of cholera in the East End.n the summer of 1831, after news had reached England that a cholera epidemic had arrived in the Baltic ports, Charles Greville said in his Memoirs [ chapter 15 ].
Cholera outbreaks in recorded history have indeed been explosive and the global proliferation of the disease is seen by most scholars to have occurred in six separate pandemics, with the seventh pandemic still rampant in many developing countries around the world.sia suffered immensely from a large outbreak from 1899-1923 and currently many developing nations in Africa, the Caribbean and Asia suffer in the seventh pandemic of cholera. This current pandemic began in South Asia in 1961, touched Africa in 1971 and then the Americas in 1991.
