The olefins contained an EWG nitrile group and varying EDGs and the effect of varying EDGs on the rate of the addition reactions was observed. The process studied was: The process studied was: The rate of the addition reaction was accelerated by the following EDGs in increasing order: H < CH 3 < OCH 2 CH 3 .
Chemical warfare protective clothing. Chemical protective clothing (CPC) is clothing worn to shield those who work with chemicals from the effects of chemical hazards that can cause injuries on the job. It provides a last line of defense for chemical safety; it does not replace more proactive measures like engineering controls. [1]

The strength of the electron-withdrawing group is inversely proportional to the pKa of the carboxylic acid. [2] The inductive effect is cumulative: trichloroacetic acid is 1000x stronger than chloroacetic acid. The impact of the EWG on pKa decreases with distances from the carboxylic group.

Only the dimer form is available for +M effect. However, the dimer form is less stable in a solution. Therefore, the nitroso group is less available to donate electrons. Oppositely, withdrawing electron density is more favourable: (see the picture on the right). The -M effect of the nitroso group. As a result, the nitroso group is a deactivator.
It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment.
