When an alkyl halide is allowed to react with a sodium alkoxide,the product most likely is:

Write the reaction steps for the following conversions:
$1.$ Propene to Propanal
$2.$ Ethanol to tert-Butyl ethyl ether

The major product of the following reaction is:

In the following reaction: $Cl-CH_2-CH(O)^{14}CH_2 \xrightarrow{C_2H_5O^-} \text{the final product is:}$

Methyl vinyl ether,$H_2C=CH-OCH_3$,reacts with $Br_2/CH_3OH$. If methanol is reacting as water would,and if this reaction follows a typical mechanism of electrophilic addition,what would be the expected product?

Give the major products that are formed by heating each of the following ethers with $HI$.
$(i)$ $CH_3-CH_2-CH(CH_3)-CH_2-O-CH_2-CH_3$
$(ii)$ $CH_3-CH_2-CH_2-O-C(CH_3)_2-CH_2-CH_3$
$(iii)$ $C_6H_5-CH_2-O-C_6H_5$
