Write a mechanism for the cleavage of butyl isopropyl ether with hi at 100°c to form exclusively isopropyl alcohol and 1-iodobutane. explain why butyl alcohol and isopropyl iodide are not formed in the reaction.

Explanation:

In this reaction, the ether is cleaved by SN2 , as I⁻ is a strong nucleophile

So we have the following steps

Now, even though butanol can become a leaving group in this reaction, this is unfavourable, as isopropyl group has large steric hindrance which prevents nucleophilic attack on isopropyl side of the ether.

its first and third is your answer i did the qustion the fourth isnt right

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
