Methane
, in which the carbon has four bonds to hydrogen, is the most reduced member of the group. The compounds become increasingly oxidized as we move from left to right, with each step gaining a bond to oxygen and losing a bond to hydrogen.
Which of the following compound is the reduced form of the carbon?
The most reduced form of carbon is
CH4
, the most oxidized is CO2.
How to tell if a compound can be oxidized?
Oxidation numbers represent the potential charge of an atom in its ionic state. If an atom's oxidation number decreases in a reaction, it is reduced.
If an atom's oxidation number increases, it is oxidized
.
Which of the following is a compounds?
Water
is a compound. A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
Is o2 a reduced compound?
Combustion reactions are redox reactions because
elemental oxygen (O
2
) acts as the oxidizing agent and is itself reduced
.
Is N2 a reduced compound?
N2 is reducing with decrease in oxidation state
. Overall, N2 is the oxidizing agent. It is making H2 to lose electrons which N2 is gaining and getting reduced.
Which class of compounds is most oxidized?
- Thus, the CHO group is more highly oxidized than the CH2OH group.
- C-1 in the alcohol group has two H atoms attached, while C-1 in the aldehyde group has one H atom attached.
- Therefore, the CHO group is more highly oxidized than the CH2OH group.
In which of the following compounds oxidation number of carbon is zero?
Hence, the oxidation state of carbon is zero in
C6H12O6
.
Which of the following transition metal has zero oxidation state?
In
[Fe(CO)5]
, transition metal Fe has zero oxidation state.
Is NAD+ oxidized or reduced?
The cofactor is, therefore, found in two forms in cells:
NAD+ is an oxidizing agent
– it accepts electrons from other molecules and becomes reduced. This reaction, also with H+, forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD.
Which is good reducing agent?
Good reducing agents include the active metals, such as
sodium, magnesium, aluminum, and zinc
, which have relatively small ionization energies and low electro-negativities. Metal hydrides, such as NaH, CaH
2
, and LiAlH
4
, which formally contain the H
–
ion, are also good reducing agents.
Which is oxidized and which is reduced?
The substance that loses electrons is being oxidized and is the reducing agent
. The substance that gains electrons is being reduced and is the oxidizing agent.
Which one of the following is not a compound?
Detailed Solution
Iron
is not a compound. Iron is an element, and not a mixture or solution compound or heterogeneous. An element is formed by atoms with exactly the same properties, that is, it consists of exactly the same atoms as an element.
Is hydrogen sulphide a compound?
hydrogen sulfide
, colourless, extremely poisonous, gaseous compound formed by sulfur with hydrogen (see sulfur).
Is O2 a compound?
The oxygen molecule O2 is considered a molecule but
not a compound
. This is because O2 is made of two atoms…
Is zinc a reducing agent?
Yes, Zn is a reducing agent
. The reducing agent is defined as a substance,that causes reduction by losing electrons. In other words, reducing agent is a susbtance, which should be oxidized. In this process, the zinc acts as a reducing agent.
Is CL oxidized or reduced?
| Substance oxidized Substance reduced | is the reducing agent is the oxidizing agent |
|---|
Is CO2 oxidized or reduced?
The most reduced form of carbon is CH4,
the most oxidized
is CO2.
Is H2 a reducing agent?
As explained, O2 when gas makes other like H2 gas to lose electrons, therefore, O2 gas is an oxidizing agent and H2 when gas loses electron in redox reaction, therefore
H2 gas is a reducing agent
.
Is clo2 a reducing agent?
CO
2
cannot act as reducing agent
because C in CO
2
has an oxidation state of +4 . C can have a maximum of +4 oxidation state, it cannot increase the oxidation state beyond +4 thus CO
2
cannot undergo oxidation thus it cannot act as a reducing agent.
Is NO3 a reducing agent?
CuS(s) is the substance oxidized => CuS(s) is the reducing agent. – is the substance reduced =>
NO3 – is the oxidizing agent
. Note : The procedure is exactly the same for balancing an oxidation-reduction reaction in basic solution except for step 2c where the charge is balanced by adding OH– instead of H+.
Which functional groups can be reduced?
Carboxylic acids, esters, and acid halides
can be reduced to either aldehydes or a step further to primary alcohols, depending on the strength of the reducing agent; aldehydes and ketones can be reduced respectively to primary and secondary alcohols.
What is reduction in chemistry?
reduction,
any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased
. The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized.
Why do reduced compounds have more energy?
Oxidation occurs when a molecule loses an electron or increases its oxidation state. When a molecule is oxidized, it loses energy. In contrast, when a molecule is reduced,
it gains one or more electrons
. As you might have guessed, the molecule gains energy in the process.
Which of the following species can function both as oxidising and reducing agent?
In
SO2
, the O. N. of S is +4 which is neither highest (i.e. , +6) nor lowest (i.e., -2) . Thus, it can act both as an oxidizing and a reducing agent.
What is the oxidation number of O in h2o2?
Hence, the oxidation number of oxygen in H
2
O
2
is
-1
. Oxygen usually shows a -2 oxidation state in most of its compounds. But exceptions are seen in the compounds such as peroxides and superoxides.
In which of the following compounds is the oxidation state of carbon equal to 4?
So unlike metals, which are almost always in a positive oxidation state, the oxidation state of carbon can vary widely, from -4 (in
CH4
) to +4 (such as in CO2).
