The mechanism for nucleophilic addition to aldehydes and ketones under different reaction conditions is that Before a weak nucleophilic assault may happen, the target must undergo protonation.
A nucleophile establishes a sigma bond with an electron-deficient molecule in a chemical addition process known as a nucleophilic addition reaction. The ability to transform carbonyl groups into a variety of functional groups makes these reactions crucial in organic chemistry.
An intermediate alkoxide is created by the breakdown of the p link to the O. The intermediate alkoxide is protonated to produce an alcohol derivative.
Therefore, the order changes to II > V > I > IV > III because nucleophilic addition is directly proportional to the electron deficiency on the carbonyl carbon.
The addition of the nucleophile and H across the C=O double bond is the outcome of all forms of nucleophile reactions.

When heating a liquid on the stovetop, the heated liquid becomes less dense and rises and the denser cooler liquid sinks to the bottom. What type of thermal energy transfer is occurring?.
The type of heat energy transfer that occur is convection
What is convection?Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.
Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink to the bottom.
Similarly with air, hot air tends to move to a cooler region due to convection
Other mode of heat transfer are conduction and radiation.
Therefore mode of heat transfer in a liquid and gas is known as convection

Time to Reflect…Consider everything you’ve learned in lab and lecture about periodic trends. In your own words, explain why it is important to know how the periodic table is organized. How do you think knowledge on periodic trends (ionization energy, electron affinity, atomic radius, electronegativity, etc.) help you, personally, in your future as scientist and/or engineer? 10. Explain how the reactivity with acid relates to the location of the metals on the periodic table.
Caesium(Cs) is the most reactive alkali metal in the group I than the francium due to the atomic radius, effective nuclear charge and the ionization energy of the caesium element.
Ionization energy is the energy requires to remove valence electron from the outer orbital. As we goes down the group, the ionization energy is decreased. This is occurred because as we goes down the group, the distance between outermost orbital and nucleus is increased. Therefore, it has lower ionization energy than other elements in the group.
Atomic radius of the element is the distance between the nucleus and the electron present in the outermost orbital. As we goes down the group, atomic radius is decreased. Therefore, it easily donates electrons and due to this, caesium is more reactive.
Fracium is really heavy element and there are many positive charges present in the nucleus of the francium. Due to the presence of more positive charges, electrons in the francium revolve at a speed of light. The electrons in the francium are closer to the nucleus than the caesium and it is harder to remove valence electrons in the caesium.
Therefore, caesium is reactive than the francium due to the ionization energy, atomic radius and effective nuclear charge.

Before paring first the electrons go into an empty orbital. Due to the negative charge of electrons, electrons are attracted to one another. To reduce repulsion, the electrons do not share orbitals.

If we use the NaCl crystal structure for the minimum cation to anion radius ratio for a co-ordination number of 6, then its ratio is 0.414.
In the given problem, we need to find out the cation-anion ratio of a co-ordination number 6. In the attached image, we can see the one of the face of rock-salt structure in which cation and anion just touch along the edges, and face the diagonals.
In the face of rock salt, we can see that triangle FGH is formed and the GF is equal to 2ra because it is divided in two atoms. Hence GF=2a and
FH=GH=ra+rc
Since FGH is a right angle triangle and according to pythagoras theorem
(ra+rc)²+(ra+rc)²=(2ra)²
2(ra+rc)²=4ra²
(ra+rc)²=4ra²/2
Take square root on both side
ra+rc=2ra/√2
Divide both side by ra
(ra+rc)/ra=2/√2
1+(rc/ra)=2/√2
rc/ra=(2/√2)-1
rc/ra=(2/1.414)-1
rc/ra=1.414-1
