Question 4

Which statement correctly explains the difference in the rates of hydrolysis between 1-chlorobutane and 1-bromobutane?

A

1-chlorobutane is hydrolysed faster because the C−Cl\text{C}-\text{Cl}C−Cl bond is more polar than the C−Br\text{C}-\text{Br}C−Br bond.

B

1-bromobutane is hydrolysed faster because the C−Cl\text{C}-\text{Cl}C−Cl bond enthalpy is greater than the C−Br\text{C}-\text{Br}C−Br bond enthalpy.

C

1-bromobutane is hydrolysed faster because chlorine is more electronegative than bromine.

D

1-chlorobutane is hydrolysed faster because the C−Br\text{C}-\text{Br}C−Br bond enthalpy is greater than the C−Cl\text{C}-\text{Cl}C−Cl bond enthalpy.
