Is Cl Or Br More Reactive?

Why is Br more selective than CL?

Bromination of alkanes occurs by a similar mechanism, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br..

Which is more reactive hydrogen or chlorine?

Because in hydrogen atom the distance between the nucleus and valence electron is less so that it can easily take one electron from other atom but in chlorine the radius of atom is more so it is difficult to gain one electron from other atoms.SO,hydrogen is less reactive than chlorine.

Which is more stable F or Cl?

Fluorine is having outermost Second orbital but Chlorine has outermost third orbital. … hence , Fluorine is more stable than Chlorine. also , there is a rule that states , more negative charge on more electronegative atom is always a stable atom.

Why is Cl so reactive?

Chlorine atoms have a lot of valance electrons without being complete on its own, so it has a greater need to seek it’s conjugates. That’s called Electronegativity. Halogens are highly reactive because of their electronegativity.

Why is chlorine cl2 and not CL?

Chlorine gas Cl2, like other gases – Nitrogen (N2), Oxygen (O2), and Hydrogen (H2) form diatomic molecules in nature. A single molecule of the gas contains two atoms that are linked by a covalent bond, hence the Cl2. … Cl2 is the formula of one molecule of chlorine gas. The chemical symbol of chlorine is only Cl.

How can you tell which metal is more reactive?

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions .

How does electronegativity affect stability?

If two similar sized atoms have different electronegativity values, the atom with higher electronegativity holds the electrons more tightly, and thus is more stable. … One says tight electron cloud means not reacting while the other says spread electron cloud means stability (less repulsion).

Why are larger atoms more stable?

Across every period on the periodic table the atoms get smaller as their nuclei get larger. Bigger atoms are more unstable because there is less nuclear charge on the valence electrons and so, it becomes easy for the valence electrons to come of their shell. And it initiates a reaction.

Why are tertiary hydrogens more reactive?

Why are tertiary hydrogens more reactive? … Tertiary C-H bonds are weaker than primary or secondary, so they are easier to break.

Are alkenes reactive?

Reactivity of Alkenes. Alkenes are a family of hydrocarbons (compounds containing carbon and hydrogen only) containing a carbon-carbon double bond. Alkenes are relatively stable compounds, but are more reactive than alkanes because of the reactivity of the carbon–carbon π-bond.

Why is Br less reactive than CL?

The shielding within the atom. Because a bromine atom has one more full shell than a chlorine atom, it has more shielding which means the attraction between the nucleus and an electron is weaker.

Is CU reactive?

The reactivity series lists metals in order of their reactivity. … The wedge shapes indicate how reactive they are. Copper is the only metal apart from precious metals that will not react with water or dilute acids. It will react very slowly with oxygen.

Is fluorine very reactive?

Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.

Is Zinc highly reactive?

Zinc. Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table. … It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen.

WHY IS F more acidic than Br?

Fluorine is most electronegative and thus would cause the compound to be the strongest acid, thus (A) is the correct answer.

Why are alkanes unreactive?

Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from their reaction with oxygen in the air – which we call burning or combustion.

What metal is the least reactive?

PlatinumPlatinum is the least reactive metal.
