Which Of The Following H Atom Is Most Reactive For Chlorination?

We know that there are three types of hydrogen atoms in the alkane, i.e., primary, secondary, and tertiary. The relative reactivity given is 1: 82: 1600 of primary, secondary, and tertiary hydrogen means the amount of the tertiary compound will be very high as compared to the amount of the primary compound.

What is the relative reactivity of chlorine?

Explain how these results will lead to a conclusion about the relative reactivity of the halogens. State the order of reactivity of the halogens. The reactivity of the halogens decreases down the group. Therefore, chlorine is more reactive than bromine and bromine is more reactive than iodine.

How do you calculate the relative reactivity of hydrogen?

The relative reactivity is calculated by dividing the percent of a compound (as determined by the GC) by the statistical factor of that compound. The statistical factor is the number of hydrogens available for reaction at each of the carbons.

What does relative reactivity mean?

Relative reactivity. The concept of reactivity means the relative activity of a chemical compound when reacting with other compounds. To provide a ‘fair’ test the compounds are usually compared with a specific ‘standard’ compound.

Why is tertiary hydrogen more reactive?

The reason for the ordering is that tertiary radicals have a lower energy (and are thus easier to form) than secondary radicals, which are in turn easier to form than primary radicals.

What is chlorine reactivity?

Chlorine is intermediate in reactivity between fluorine and bromine, and is one of the most reactive elements. Chlorine is a weaker oxidising agent than fluorine but a stronger one than bromine or iodine. … Chlorine tends to react with compounds including M–M, M–H, or M–C bonds to form M–Cl bonds.

How do you calculate relative reactivity?

The relative reactivity of a group of metals can be established by comparing the reaction of each metal with a given reagent. A metal might react with a specific reagent or no reaction may occur. On the other hand, a given metal might react with a specific reagent at a different rate than some other metal.

Why is chlorine more reactive than bromine?

Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …

Why is secondary hydrogen more reactive than primary hydrogen?

Radical formation is under kinetic control, so abstraction of the 2° hydrogen to form the 2° radical must be faster than abstraction of the 1° hydrogen to form the 1° radical. than the primary hydrogens under these conditions! The secondary hydrogens are 4.5 times more reactive than the primary hydrogens.

What are secondary hydrogens?

A secondary (2º) hydrogen is a hydrogen atom residing on a secondary carbon in an organic species. see also primary hydrogen, tertiary hydrogen.

How many secondary hydrogens are there?

There are two hydrogen atoms attached to the secondary carbon. Therefore, two secondary hydrogen atoms are present in the molecule.

What is the relative reactivity of the halogens?

The halogens include fluorine, chlorine, bromine, iodine, and astatine. All of these elements are considered to be reactive nonmetals. … All members of the halogen family have seven valence electrons. Because these atoms are so close to having a full set of eight valence electrons, they’re very reactive.

Which of the following order is correct for the reactivity of indicated H atoms?

For the given reaction the correct reactivity order of H-atoms is
=”https://d10lpgp6xz60nq.cloudfront.net/physics_images/RES_ORG_RK_JA_FST1_E01_1859_Q01.png” width=”80%”> Reactivity depends upon stability of free radicals generated at y,zx and w respectively.

What is chlorination of methane?

If a mixture of methane and chlorine is exposed to a flame, it explodes – producing carbon and hydrogen chloride. … The reaction we are going to explore is a more gentle one between methane and chlorine in the presence of ultraviolet light – typically sunlight.

Why do you determine the relative reactivities of metals?

By systematically observing the displacement reactions among a series of metals and solutions of their cations, it is possible to determine the relative oxidation potentials of the metals. … The metal with the higher reduction potential will reduce a cation of a metal with a lower reduction potential.

What is the reactivity series?

The reactivity series is a series of metal elements, and sometimes carbon and hydrogen, that is arranged according to their reactivity. A reactivity series is typically a vertically presented model with the most-reactive element placed at the top of the series and the least-reactive element placed at the bottom.

How do you determine the reactivity of an element?

Place each of the metals in turn in a clean test-tube containing water and labeled with the symbol of the metal added. If bubbles of a gas are evolved, test the gas with a lighted match, this is called the pop test.

How does chlorine oxidize?

Chlorine kills bacteria though a fairly simple chemical reaction. … Both kill microorganisms and bacteria by attacking the lipids in the cell walls and destroying the enzymes and structures inside the cell, rendering them oxidized and harmless. The difference between HOCl and OCl is the speed at which they oxidize.

What element combines with chlorine?

Chlorine combines with all elements except the noble gases. Here, it reacts with sodium. number of neutrons in the atom of any one element can vary.

What is the molecular formula of chlorine?

Molecular formula of chlorine is Cl2 Draw electrondot class 11 chemistry CBSE.

What is the rate of replacement of hydrogens of alkanes?

Rate of replacement of hydrogens of alkanes is : 3°> 2° > 1°.

Is tertiary more reactive?

Reactivity of alkyl halides: … In the $ {S_N}1 $ mechanism, tertiary alkyl halides are more reactive. A tertiary carbocation is more stable than a secondary carbocation which is more stable than a primary carbocation.

Why direct fluorination is not possible?

The reaction of alkanes with fluorine is difficult to control because the activation energy for hydrogen abstraction is so low. The initiation step involves the homolytic cleavage of the F-F bond.
