Haloalkanes

Question 1

What affects the rate of hydrolysis for haloalkanes(4)

Answer 1

• The strength of the C-Halide bond; decreases down the group. Weaker bond= quicker hydrolysis. Less energy needed to break bond
• Stability of the Haloalkane: tertiary> secondary> primary
• primary is slowest as it is less stable and involves one step mechanism compared to tertiary’s 2 step mechanism

Question 2

Mechanism for alkane to Haloalkane?

Answer 2

• Radical substitution
