Help me out plz, I will mark you the brainiest.

Answer : The correct option is (B).

Explanation :

Isomer : It is defined as a molecule have the same molecular or chemical formula but the different chemical structure or shape.

The given compound has 4 carbon atoms and also saturated compound because there is no double or triple bond present.

As we know that there are two structural isomers of butane.

(1) n-butane

(2) iso-butane

Thus, the correct option is (B).

it should be all of them because it asks if you included all of those in your answer

explanation:

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
