The protons in acetylene (C2H2) are very weakly acidic. With a strong base (eg. sodium hydride, NaH), they can be abstracted, giving the corresponding metal acetylide (NaC2H, and Hydrogen, H2).

Why acetylene is stronger acid Than ethylene?

Acetylene (C2H2) is a stronger acid than ethylene (C2H4) because the hydrogen in acetylene is more acidic due to the presence of a triple bond between the carbon atoms, leading to a greater electron-withdrawing effect. This results in a more polarized and weaker C-H bond in acetylene compared to the C-H bond in ethylene, making acetylene more prone to releasing a proton.


C2h4 and c2h2 which one is acidic?

C2H2 (acetylene) is the more acidic compound compared to C2H4 (ethylene) due to the presence of a triple bond between carbon atoms in acetylene, making it more willing to donate a proton and behave as an acid.


Is acid a proton donor or acceptor?

Acid is a proton donor.


Is an acid a proton donor or acceptor?

An acid is a proton donor.


An acid that forms when a base gains a proton?

The acid formed when a base gains a proton is called a conjugate acid of the base. This process is known as protonation, where the base accepts a proton to become an acid. The conjugate acid will have one more proton than the base.


What is transferred between a conjugate acid base pair?

In a conjugate acid-base pair, a proton (H+) is transferred between the members of the pair. The acid donates a proton to become its conjugate base, while the base accepts a proton to become its conjugate acid.


What theory describes an acid as a proton and a base as a proton acceptor?

The theory that describes an acid as a proton donor and a base as a proton acceptor is the Brønsted-Lowry acid-base theory. In this theory, an acid is defined as a species that donates a proton (H+), while a base is a species that accepts a proton. This theory is widely used in understanding and predicting acid-base reactions.


Is a conjugate acid formed when a base gains a proton?

Yes, when a base gains a proton, it forms its conjugate acid by accepting the proton. The conjugate acid of a base is the species that results after the base gains a proton.


What happen in a bronoted lowry acid base reaction?

In a Brønsted-Lowry acid-base reaction, a proton (H+) is transferred from the acid to the base. The acid acts as a proton donor, while the base acts as a proton acceptor. This proton transfer results in the formation of a conjugate base from the acid and a conjugate acid from the base.


Is sulfuric acid a bronsted acid bronsted base or both?

Sulfuric acid is a Bronsted acid because it donates a proton (H+) in an acid-base reaction. It can act as a proton donor but not as a proton acceptor, which is the characteristic of a Bronsted base.


A conjugate acid is the species that?

remains after an acid has given up a proton


What are the bronsted - lowry definition of acid and base?

Arrhenius: Acid is a proton (H+) donor. Base is a -OH^- (hydroxyl) donor.B-L: Acid is a proton donor. Base is a proton acceptor.
