Which is most acidic hydrogen?

β− hydrogen atom of carbonyl compounds is more acidic in nature than α hydrogen.

Is ethyne a stronger acid than ethene?

Why is Ethyne a Stronger Acid than Ethane or Ethene? If we compare acid strengths of the simple hydrocarbons, we find that ethyne is substantially more acidic than ethene or ethane in the gas phase or in solution.

Which of the following has acidic hydrogen A ethane B ethene C ethyne D benzene?

As s character is highest in sp hybridized carbon , the electronegativity of carbon is highest as s orbital lies near to nucleus and thus withdraws electrons from hydrogen and easily releases ions and thus act as acid. Thus acidic hydrogen is present in ethyne.

Which of the following is the most acidic ethane ethene ethyne ammonia?

The order of acidic nature would be: water > ethyne > ammonia > ethane. Since oxygen has highest electronegativity amongst the atoms of the compounds, so its hydrogen will be most acidic and hence will be best acid among them.

Which carbon has the most acidic hydrogen?

Which is more acidic ethene or ethane?

In ethyne carbon is sp hybridised but in ethane carbon is sp3 hybridised. s-character increases acidic strength increases thus ethyne is more acidic than ethane.

Which is more acidic ethyne or ethene and why?

With increasing the s character in the hybridization electronegativity of the carbon increases and vice-versa. And In ethyne structure the hybridization of each carbon is sp. Therefore, the acidity order should be, ethyne>ethene. Note: Acidity of carboxylic acids are much more than ethyne.

Which of the following alkynes is most acidic?

Thus $CH \equiv CH$ that is ethyne is the most acidic of all four compounds. Hence the correct option is D.

Does ethene contain acidic hydrogen?

Ethene is less acidic than Ethene as the carbon containing hydrogen is sp2 hybridised (\%s character is 33.3, hence less electronegative).

Which is more acidic ammonia or ethene?

Of you remove a proton from CH2=CH2, you get [CH2=CH]- or ethylide ion. More is the s-character, more is the acidity. Ammonia has 25\% s-character (sp3 hybridised) while ethylene has 33\% s-character (sp2 hybridised). Hence, ethylene is more acidic.

Which is more acidic methane or ethene?

Methane is more acidic than ethane.
