Acetyl chloride does not react with

Hybridisation of oxygen in diethyl ether is

What is the temperature at which ethers can be prepared from alcohols by the action of concentrated $H_2SO_4$ (in $K$)?

Main products formed during a reaction of $1-$methoxy naphthalene with hydroiodic acid are:

Ethers,when dissolved in cold concentrated sulfuric acid,form:

Assertion: Ethyl phenyl ether on reaction with $HBr$ forms phenol and ethyl bromide.
Reason: Cleavage of $C-O$ bond takes place at the ethyl-oxygen bond due to the more stable phenyl-oxygen bond.
