Question 3

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

A

1-chlorobutane is hydrolysed faster because the chlorine atom is more electronegative than the bromine atom.

B

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

C

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.

D

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