Which compounds give one singlet in the 1H NMR spectrum? CH3CH3 1461113dichloro22dibromo 1461123dimethyl2butene CH3―C≡C―CH3 CH2═CHCH═CH2 14611cyclohexadione 14611cyclopentane 14611123tribromopropane 14611ketone 14611ester

CH3CH3, 1,3- dichloro-2,2- dibromo, 2-butyne, cyclopentane, 2,3- dimethylbut-2-ene, 2,2,4,4- tetramethlpenta-3-one.

Explanation:

This problem or question has to do with spectroscopy. Spectroscopy is one of the Important aspect of physical Chemistry. It is important because it helps in the identification of chemical samples or compounds. The Nuclear Magnetic field work generally on the principle of absorption of energy.

The following compounds as given in the question above shows singlet in the 1H NMR spectrum.

(1). CH3CH3: shows singlet in the 1H NMR spectrum at 0.86 ppm.

(2). 1,3- dichloro-2,2- dibromo; shows singlet.

(3). 2- butyne shows singlet

(4). Cyclopentane shows singlet.

(5). 2,3 - dimethylbut-2-ene shows singlet.

(6). 2,2,4,4- tetramethlpenta-3-one shows singlet.

Kindly note that I have used the IUPAC naming system to name the Compounds in the question above.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
