Draw the structures for the following compounds:
2-methylpropane

Structure of 2-methylpropane.

Explanation:

The given compound is 2-methyl propane.

Propane has three carbons in their parent chain and all are bonded by a single bond.

And the second carbon has methyl group.

The structure of 2- methyl propane is as follows.

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
