What is chromic acid test?
The chromic acid test uses the Jones reactant to oxidize aldehydes and alcohols and reduce the chromic acid, resulting in a color change.Positive chromic acid test is indicated by disappearance of orange color from chromic ions and appearance of blue-green color from Chromium (III) ion (reduction of chromium ion from [tex]CrO_4^- \text{to } Cr^{3+}[/tex])Positive chromic test indicated functional groups that can be oxidized.
⇒Cyclohexanol can be oxidized to become cyclohexanone.
⇒Pentan-3-ol can be oxidized to become pentan-3-one.
Hence, both B and C will show positive chromic acid test.
A) tert-butanol although contains alcohol functional group, cannot be further oxidized as it is a tertiary alcohol.

If a stronger solution of sodium bicarbonate was used in beaker C, would it require more or less hydrochloric acid to neutralize and why?
Part A; A stronger solution of sodium bicarbonate require more hydrochloric acid will be required
Part A; The reason why more HCl is required is due to the presence of more hydroxyl ions in the solution
The reason arriving at the above responses are as follows;
Part A
Sodium bicarbonate, NaHCO₃, is baking soda = A basic salt; has the capacity to deprotonate water
Hydrochloric acid, HCl = An acid
The reaction between sodium bicarbonate and hydrochloric acid is presented as follows;
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
The equation for the ionic reaction is as follows;
Na⁺(aq) + HCO₃⁻(aq) + H⁺(aq) + Cl⁻(aq) → Na⁺(aq) + Cl⁻(aq) + H₂O(l) + CO₂(g)
In water, we have;
HCO₃⁻(aq) + H₂O(l) ⇄ H₂CO₃(aq) + OH⁻(aq)
The presence of a stronger solution of sodium bicarbonate, will produce more hydroxyl ions, OH⁻(aq), which will require, more HCl to neutralize
Therefore, if a stronger solution of sodium bicarbonate was used, more hydrochloric acid will be required
Part B
The solution of stronger sodium bicarbonate will contain a higher concentration of hydroxyl ions and therefore, require more HCl, to neutralize

a. Phenol (C6H5OH) is an aromatic compound and a colourless liquid widely used in household products
and medicine. When it reacts with chlorine liquid (chlorine is a diatomic molecule), in the presence of a
catalyst, one of the aromatic hydrogen atoms attached directly to a C atom is replaced with a chlorine
atom, and liquid chlorophenol is formed. This replacement process is called chlorination
Write a balanced chemical equation for the chlorination reaction and explain how you balanced it. Note
that hydrogen chloride gas (HCI) is also a product of this chemical reaction and you should ignore the
presence of the catalyst in the equation.
Because there are 2 Cl on the left, we will put a coefficient 2in front of HCl on the right side to balance out the Cl. This would result in an unequal amount of H, with 6 on the right side and 7 in the left, so we have to put a coefficient of 2 in front of C6H5OH and C6H4OH on both sides to balance out the H. By doing this, we would obtain an equal amount of H on both sides. The Carbon is already balanced, and so is the Oxygen.
The balanced chemical reaction equation for the reaction between aromatic phenol and chlorine gas in the presence of FeCl3 as catalyst is as follows;
C6H6O + Cl2 -------> C6H5OCl + HCl
An aromatic compound has 4n + 2 number of pi electrons. This condition is satisfied by phenol. Hence, phenol has the stability associated with aromatic compounds.
The reaction of phenol with chlorine in the presence of a catalyst such as FeCl3 is an aromatic electrophillic substitution reaction.
This reaction yields a chlorinated phenol (one of the aromatic hydrogen atoms attached directly to a C atom is replaced with a chlorine atom and chlorophenol is formed).
A balanced chemical reaction equation is one in which the number of atoms of each element at the reactant side and the product side are equal. This condition is satisfied for the reaction;
C6H6O + Cl2 -------> C6H5OCl + HCl

How does the carbonyl group increase the reactivity of carboxylic acids?
Answer:
The relative reactivity of carboxylic acid derivatives toward nucleophile substitutions is related to the electronegative leaving group's ability to activate the carbonyl. The more electronegative leaving groups withdraw electron density from the carbonyl, thereby increasing its electrophilicity.

Which statement about an atom is correct? (1 point)
O The proton has no charge and is found in the nucleus.
O The neutron has no charge and is found outside of the nucleus.
O The neutron has a negative charge and is found in the nucleus.
o The electron has a negative charge and iş found outside of the nucleus.
Answer:
D. the electron has a neg. charge and is found outside of the nucleus.
Explanation:
the proton has a positive charge, while the neutron has no charge at all. both are found in the nucleus.
the electron has a negative charge, but stays outside of the nucleus in the electron cloud, constantly moving around.
Taking into account the constitution of an atom, the correct statement is "The electron has a negative charge and iş found outside of the nucleus."
An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
Every atom consists of:
A nucleus in which neutrons and protons meet. Energy levels where electrons are located.In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.
The neutron is an electrically neutral subatomic particle, while the proton has a positive electrical charge. Electrons have a negative charge, move around the nucleus at different energy levels and are attracted to protons, positive in the atom through electromagnetic force.
In summary, the correct statement is "The electron has a negative charge and iş found outside of the nucleus."
