When we write
log
a
b
=
c
, we ask to what power we raise the base,
a
, to get
b
; here
a
c
=
b
. The normal bases are
10
,
(common logarithms)
, and
e
,
(natural logarithms)
.
Thus when we write
log
10
(
10
−
5
)
, we are asking to what power we raise
10
to get
10
−

. Now clearly the answer is
−

, i.e.
log

You shouldn't need a calculator, but use one if you don't see it straight off.
Answer:
t-butyl cation
Explanation:
Generally a dehydration reaction occurs when an organic compound loses water molecules to form alkenes. However, in an acid-catalyzed dehydration, the dehydration reaction occurs in the presence of an acidic compound which acts as a catalyst. Therefore, for this specific case, the hydride will migrate and a t-butyl cation will be formed. This is because it is more stable due to the presence of three electron releasing alkyl groups which can stabilize a positive charge compared with the secondary cation formed when the methyl group migrates.
Answer:
First one is: ammonia
Second one is: calcium hydroxide
Explanation:
Answer:
Experiments to determine mechanisms involve looking at indirect evidence to help support or disprove a proposed mechanism.
Most intermediates are not typically isolated to determine reaction mechanisms.
Carbocations are very reactive and are typically not isolated for analysis.
Scientists can prove that a specific mechanism exists.
Evidence of intermediates sometimes can be seen using techniques such as nuclear magnetic resonance spectroscopy
Explanation:
The study of reaction mechanism and chemical kinetics often form the main thrust of study in organic, inorganic and physical chemistry.
We often want to know the actual processes involved in the conversion of one specie to another. Unfortunately, this information may have to be obtained indirectly by certain chemical reactions or by the use of new instrumental methods such as nuclear magnetic resonance spectroscopy.
Many organic reactions have carbocation intermediates. These carbocations are relatively short-lived and are transient intermediates which are rarely isolated unless they are isolated in a molecular cage using a macromolecule or in superacids.
By intensive study, scientists can proof or disprove the authenticity of any proposed mechanism.
We must know that a transition state has partial bonds. It is often an extremely short-lived specie which cannot be isolated.
