The reaction rate order for sn1 reaction rate will be CH3F < CH3Cl < CH3I. The reason for this is that the halide with the weaker nucleophile will have a higher sn1 reaction rate.

The nucleophile is a key factor in determining the rate of an Sn1 reaction. In general, the stronger the nucleophile, the faster the reaction will be. This is because the stronger nucleophile will be able to break the bond between the alkyl halide and the nucleophilic carbon more easily. For this reason, the order of increasing Sn1 reaction rate will be CH3F < CH3Cl < CH3I.

0.300 g of primary standard grade of sodium carbonate was required

what is primary standard grade ?

A primary standard in chemistry is a reagent that is exceedingly pure, indicative of the amount of moles in the material, and readily weighed. A reagent is a material that is used to initiate a chemical reaction with another substance. Reagents are frequently used to test for the presence or amount of certain compounds in a solution. Primary standards are commonly employed in titration and other analytical chemistry procedures to determine an unknown concentration. Titration is a chemical reaction that happens when modest quantities of a reagent are introduced to a solution. The reaction proves that the solution has a specified concentration. Primary standards are frequently used to create standard solutions, which have a specific concentration.

A good primary standard fulfils the following requirements:

Has a high purity level

It has a modest reactivity.

It has a large comparable weight.

Is unlikely to collect moisture from the air (hygroscopic) in order to decrease mass fluctuations in humid vs dry settings.

Is harmless, cheap, and widely accessible.

The concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution. Therefore, molarity of diluted solution is 0.27M.

Molarity can be calculated by dividing number of moles of solute by volume of solution in liter. Molarity is affected by temperature. Its unit is mole/liter. It measure the concentration of any solute in a solution.

Mathematically,

According to the neutralization law,

M₁V₁=M₂V₂

where,

M₁ = molarity of stock solution =1.50M

V₁ = volume of stock solution =  59.0 ml

M₂ = molarity of dilute solution =?

V₂ = volume of dilute solution =228ml

substituting all the given values we get

M₁V₁=M₂V₂

1.50M×59.0 ml=M₂×228

M₂=0.38M

Again diluting this solution

M₂×V₂=M₃×V₃

0.38×114=M₃×159

M₃=0.27M

Therefore, molarity of diluted solution is 0.27M.

The answer is paper chromatography using different solvents with a range of polarities as the mobile phase.

Paper chromatography- Low-molecular-mass molecules can be separated using paper chromatography based on how evenly they are distributed in the stationary and mobile phases. Paper chromatography is regarded as a potent analytical technique because of its low cost and the availability of numerous procedures for the separation of chemicals.

A small amount of a sample solution is poured onto a strip of chromatography paper in a paper chromatography experiment. After that, a solvent is used to suspend the chromatography paper. The sample solution's constituent components split out into bands of distinct hue as the solvent goes up the paper.

The speed of the chromatography process is influenced by the solvent's polarity. Therefore, we may conclude that all of the other components in the mixture move more quickly during the chromatography experiment if the solvent's polarity is increased.

Thus, answer is paper chromatography using different solvents with a range of polarities as the mobile phase.

Though NaBH4 and LiAlH4 are similar, NaBH4 is less reactive. Esters, amides, acids, and nitriles are largely unaffected; its power is limited to reducing aldehydes, ketones, and acid chlorides to alcohols.

Because the hydride ion can attack the planar carbonyl group on either face, the reduction of unsymmetrical ketones with LiAlH4 or NaBH4 results in the production of two stereoisomers: A racemic mixture of enantiomers results from the absence of any additional chiral centers. The intermediates produced by the reaction of sodium borohydride with water are also mild reducing agents known as hydroxyborohydride. The most popular reaction solvents for reduction or organic substrates are ethanol and propane-2-ol, though methanol is also employed.

Each alkyl halide stereoisomer gives a different alkene in the E2 reactions that follow because of the anti-coplanar conformation requirement for the E2 reaction, one stereoisomer will be produced preferably over the other, and this is called stereoselectivity.

Stereoselectivity means the specific formation of either (E) - or ( Z )-alkenes. Unlike the E1-reaction, which has only poor stereoselectivity because of the intermediate formation of a planar carbocation, the stereoselectivity of the E2 reaction is very high. In the transition state all five groups or atoms involved must be coplanar.

The first two possibilities are examples of stereoselectivity, the first being termed syn-addition, and the second anti-addition. Since initial electrophilic attack on the double bond may occur equally well from either side, it is in the second step (or stage) of the reaction (bonding of the nucleophile) that stereoselectivity may be imposed.

The two bonds appear as the two parallel lines between the O atoms. This is called a double bond. Each bond is a pair of electrons, one from each connected O atom. So the double bond, the two parallel lines, represents a total of 4 electrons.

Each O is surrounded is by four dots and two sticks or lines, representing another 4 electrons in the O2 double bond. So each O is surrounded by 8 total valence electrons, giving it an octet also and making it stable.
