Electrophilic addition to alkenes takes the following general form: nuc: = nucleophile E+ = electrophile. Electrophilic addition to alkenes starts with the pi electrons attacking an electrophile, forming a carbocation on the most stable carbon.A nucleophile then attacks the carbocation to form the product. There are many different kinds of such addition, including:lectrophilic addition to alkenes takes the following general form: nuc: = nucleophile E+ = electrophile. Electrophilic addition to alkenes starts with the pi electrons attacking an electrophile, forming a carbocation on the most stable carbon.
Selective auditory attention or selective hearing is a type of selective attention and involves the auditory system of the nervous system.
An audiological evaluation identifies the severity of your hearing loss and the frequency range in which it occurs. This information may help identify the cause of your hearing loss.
