Organic chemistry! meaning of "organic"?! initially scientists believed there was a special "force" in living organisms!-this was assumed the unique component of organic material!

program on the inert pair effect, they penetrate the core and pass close to the nucleus. during this time, there are many fewer electrons between them and the nucleus, so the shielding is reduced and they then experience a nuclear charge closer to +69 e. consequently, the average value of the effective nuclear charge is raised to the value we
