2) Consider the reaction of 1-bromopropane with a solution of sodium ethanoate to form an ester
a) Give an equation for the reaction and name the ester formed.
It is observed that when the reaction is done in solution at a high pH, another organic
product of nucleophilic substitution forms at the same time as the ester. What is the other
organic product, and will it be formed in larger or smaller amounts than the ester?
(6 marks)

(a). CH3CH2CH2Br + CH3COONa ===> CH3COOCH2CH2CH3 + NaBr

-propylethanoate or ethylpropanoate

Another organic product is CH3COOH ( ethanoic acid ).

It will be in smaller amounts than the ether

explanation:

2b2t

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
