Answer:

an increase in 1-butene was observed when t-butoxide was used

Explanation:

When a base reacts with an alkyl halide, an elimination product is formed. This reaction is an E2 reaction.

Here we are to compare the reaction of two different bases with one substrate; 2-bromobutane. Both reactions occur by the E2 mechanism but follow different transition states due to the size of the base.

The Saytzeff product, 2-butene, is obtained when the methoxide is used while the non Saytzeff product, 1-butene, is obtained when t-butoxide is used.

The Saytzeff rule is reliable in predicting the major products of simple elimination reactions of alkyl halides given the fact that a small/strong bases is used for the elimination reaction. Therefore hydroxide, methoxide and ethoxide bases give similar results for the same alkyl halide substrate. Bulky bases such as tert-butoxide tend to yield a higher percentage of the non Saytzeff product and this is usually attributed to steric hindrance.

Under what conditions would the enthalpy change of a process be equal to the amount of heat transferred into or out of the syste
Zina [86]

Answer:

at constant pressure the enthalpy change of a process equal the amount of heat transferred into or out of the system

Explanation:

∆H=∆(E+PV)

=∆E+P∆V

∆E=qp+w

w=P∆V

∆H=∆E+P

∆V=(qp+w)-w=qp

when qp= heat at constant pressure

good luck

The primitive atmosphere of Earth may have favored the abiotic synthesis of organic molecules because it __________.
ASHA 777 [7]

Answer and Explanation:

The primitive atmosphere of Earth may have favored the abiotic synthesis of organic molecules because it **had close to no oxygen, hence, it was powerfully reducing. It had pure energy sources too in form of ultraviolet rays from the sun (it was extremely hot! Too hot for water in liquid form to exist in fact!), outgassing from the numerous volcanoes and lightning**.

Abiotic synthesis means a formation reaction where the reactants are charged to become products, almost all on their own, with no catalyst especially.

So, these factors would have helped the organic molecules to form as most of what is needed to overcome the energy barrier and become products.
