Ketones and Aldehydes - Rutgers University
crab.rutgers.edualdehydes (two alkyl substituents vs. one alkyl substituent). (Aldehydes more reactive than ketones). Steric Reason The electrophilic carbon is the site that the nucleophile must approach for reaction to occur. In ketones the two alkyl substituents create more steric hindrance than the single substituent that aldehydes have.

Reactions of Alkyl Halides - Towson University
tigerweb.towson.eduAlkyl halides undergo two basic types of reactions in organic chemistry, including substitutions and eliminations. There are two types of substitution reactions and two types of elimination reactions. We will look at each individually and then try to compare and contrast so you know what identifying characteristics to look for, to help you ...

Experiment 7 — Nucleophilic Substitution
www.amherst.eduAn assortment of alkyl, alkenyl, and aromatic chlorides and bromides will be available. To encourage an SN2 reaction mechanism you will use a solution of NaI in acetone. Iodide is a good nucleophile, and if it displaces bromide or chloride, NaBr or NaCl will precipitate (these are much less soluble in acetone than NaI).
Alkyl Halides - Rutgers University
crab.rutgers.eduAlkyl halides are a class of compounds where a halogen atom or atoms are bound to an sp3 orbital of an alkyl group. CHCl 3 (Chloroform: organic solvent) CF 2 Cl 2 (Freon-12: refrigerant CFC) CF 3 CHClBr (Halothane: anesthetic) Halogen atoms are more electronegative than carbon atoms, and so the C-Hal bond is polarized.
