Which statement is correct for the different rates of hydrolysis of RBr\text{RBr}RBr and RI\text{RI}RI?
RI\text{RI}RI is hydrolysed faster because Br\text{Br}Br is more electronegative than I\text{I}I.
RI\text{RI}RI is hydrolysed faster because the C−Br\text{C}-\text{Br}C−Br bond enthalpy is greater than C−I\text{C}-\text{I}C−I.
RBr\text{RBr}RBr is hydrolysed faster because Br\text{Br}Br is more electronegative than I\text{I}I.
RBr\text{RBr}RBr is hydrolysed faster because the C−I\text{C}-\text{I}C−I bond enthalpy is greater than C−Br\text{C}-\text{Br}C−Br.
