в чем разница между ковалентной полярной и ковалентной неполярной связью

Ответы

Автор ответа: worldxasnes

1. Ковалентная полярная связь: В такой связи атомы разделяют электроны неравномерно. Один атом привлекает электроны сильнее, чем другой, из-за разницы в их электроотрицательностях. Это создает положительный и отрицательный полюса в молекуле. Примером такой связи может служить молекула воды (H2O), где кислород привлекает электроны сильнее водорода, создавая полярную молекулу.

2. Ковалентная неполярная связь: В такой связи электроны делятся равномерно между атомами, и нет различия в электроотрицательности. В результате молекула не имеет полюсов и остается неполярной. Примером такой связи может служить молекула молекуларного азота (N2), где два атома азота имеют одинаковую электроотрицательность .
