The rate of the addition reaction was accelerated by the following EDGs in increasing order: H < CH 3 < OCH 2 CH 3. When R = OCH 2 CH 3, the rate of the reaction is the fastest because the reaction has the smallest energy of activation (ΔG ‡). The ethoxy and cyano groups are able to delocalize the radical ion in the transition state, thus ...

An electron-withdrawing group (EWG) is a group or atom that has the ability to draw electron density toward itself and away from other adjacent atoms. [1] This electron density transfer is often achieved by resonance or inductive effects.
EWG is headquartered in Washington, D.C.. [2] Its lobbying organization, the EWG Action Fund (a 501(c)(4) organization) was founded in 2002. [3] EWG partners with companies to certify their products. [4] Its reports are influential with the public, but it has been criticized for exaggerating the risks of chemicals. [4] [5] [6]
User activity detection leads to the precise detection of appliances required for an activity. If an appliance is active but not required for a user's current activity, it wastes energy and can be turned off to conserve energy. The precise identification of user activities is necessary to achieve this method of energy conservation. [1]
The Protocol on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices, or Protocol II, is a United Nations treaty that restricts the use of land mines, remotely delivered mines, and booby traps.
