nucleophile replaces the leaving group in the substrate. In this lab‚ the hydroxyl group of t-butyl alcohol is replaced by a chlorine atom. The reaction proceeds through an SN1 mechanism (Weldegirma 38-41). “A nucleophile is any neutral or uncharged molecule with an unshared pair of electrons. In the substitution reaction‚ the nucleophile donates an electron pair to the substrate‚ leading to the formation of a new bond to the nucleophile‚ while breaking the existing bond to the leaving group” (Solomons

Natural selection is the process that explains this survival and shows how species can change over time. 8-2.2 Summarize how scientists study Earth’s past environment and diverse life-forms by examining different types of fossils (including molds‚ casts‚ petrified fossils‚ preserved and carbonized remains of plants and animals‚ and trace fossils).
