A bulky base prefers the elimination reaction by extracting the proton from the less hindered side of the alkyl chain and undergoing E2- elimination reaction.A less bulky base prefers the abstraction of acidic hydrogen from the more substituted, hence hindered side and undergoes E1- elimination reaction.Both the elimination reactions favor Zaitsev products unless there is a special case like, when the leaving group is charged ammonium ion, Hoffmann product is formed as major product.Base DBU is a very strong base and thus will prefer E2- elimination reaction. The major product will be the Zaitsev product.Tertiary amines are considered a strong base and so will prefer E2- elimination reaction. The major product will be the Zaitsev product.Secondary amines are considered weak bases and so will prefer E1- elimination reaction. The major product will be the Zaitsev product.The major product in general is Zaitsev product. However, the product formation also depends on the leaving group of the reactant.BaseElimination reactionMajor productDBUE2ZaitsevTertiary amineE2ZaitsevSecondary amineE1Zaitsev

PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.

This central science looks into the physical and chemical properties of matter and how these properties are connected to the structure of matter in an atomic or molecular level. The changes involved in matter are also looked at be it physical change or chemical change.
