Homework Answers
1.Open Chain ethers: The general formulae of open chain ether is
ROR'. They are not closed rings. The bond angle
is about is 110° and the C-O distance is about 140 pm. Cylclis
chain ethers are generally termed as epoxides and the simplest
epoxide is ethylene oxide. Their bond angle and bond distance
varies according to the compound. 
2.The two types of nucleophiles generally used to prepare alkyl halide by a nucleophilic substitution reaction are:
a) By an alkoxide ion which displaces the nucleophile by an SN2 mechanism.
b) When a tertiary alkyl halide is treated with a tertiary or secondary alcohol by SN1 mechanism. Here the tertiary alcohol acts a nucleophile.
3.A method for the preparation of an epoxide is by using peracid. Peracid based epoxidation is a single step process which involves the conversion of an alkene to an epoxide.It is sterioselective process. Peracid acts as oxygen supplier for epoxides to form. The general formulae of a peracid is RCO3H. The byproduct we get is an acid. Mechanism for peracid based oxidation is:

For O. Chem lab titled: "Perfumes: The Synthesis of Nerolin".
Please answer questions 16 (a-c) and 17.
Nerolin chemically is called either 2-ethoxynaphthalene or ethy! S-naphthy! ether and can be prepared by the following Williamson synthesis of ethers. OH O-CH.CH - 1-CH.CH KOH alcohol +H.O+KI Waphthal Ethyl iodide Nerolin The potassium hydroxide, acting as a base, removes the slightly acidic proton from 6-naphthol and converts it into the nucleophile potassium B-naphthoxide, which attacks ethyl iodide and displaces the iodide ion....
