Which of the following will not show tautomerism?
CH3OH.
Which of the following can show tautomerism?
The correct option is C Acetylacetone Which of the following is an isomer of 2,2- dimethyl propane?
Does c6h5coch3 show tautomerism?
Therefore, it does not show tautomerism. Hence, the correct answer is option (D).
Which among the following will show tautomerism?
The correct option is C Acetylacetone.
How many of following compounds are showing tautomerism phenomenon?
Answer will be 2.
Does benzaldehyde show tautomerism?
C6H5CHO YOUR ANSWER SOLUTION Presence of a-hydrogen atom is a necessary condition for tautomerism. Here in benzaldehyde, there is no alpha hydrogen atom present in the compound. Thus, it does not show tautomerism.
Does acetylacetone show tautomerism?
Acetylacetone is an organic compound with the chemical formula CH 3COCH 2COCH 3. It is a colorless liquid, classified as a 1,3-diketone. It exists in equilibrium with a tautomer CH 3C(O)CH=(OH)CH 3.
Which compound will show tautomerism?
Tautomers are isomers of a compound which differ only in the position of the protons and electrons. The carbon skeleton of the compound is unchanged. A reaction which involves simple proton transfer in an intramolecular fashion is called a tautomerism. This compound will show keto-enol tautomerism.
How many alpha hydrogen atoms are required for tautomerism to occur?
Ans:For an aldehyde or a ketone to exhibit tautomerism it is essential that it must have at least one α−H atom. Hence d is the correct answer. From this example we can understand that for the formation of tautomerism we should atleast have one alpha hydrogen.
What is protprotons tautomerism?
Protons are often the atoms that change position. Coming to the above compound, the tautomerism displayed is keto-enol tautomerism.
What is the difference between tautomers?
Tautomers are isomers i.e they have the same chemical formula, but different structures. In many cases, the tautomers of a compound coexist and are considered the same compound, though their structures are different. Protons are often the atoms that change position.
