The compound formed when ethyl bromide is heated with dry silver oxide is

Which products are obtained when methoxy ethane is heated with $HI$?

Consider the following reaction.
$C_6H_5-O-CH_2-C_6H_5 + HI \rightarrow \text{Product}$
Statement $I$ : In the above reaction, the product formed will be a mixture of benzyl alcohol and iodobenzene.
Statement $II$ : In the above reaction, the $-O-CH_2-$ bond is cleaved to give the product.
In the light of the above statements, choose the correct answer from the options given below:

The major product in the given reaction will be:
(One mole of each)
$C_6H_5O^-Na^+ + C_6H_5CH_2Cl + C_2H_5OK^+ \xrightarrow{\text{Major Product}}$

Consider the reaction of $HI$ with the following compounds:
$I$: Tetrahydropyran
$II$: Isochroman (or similar cyclic ether fused to benzene)
Which forms a di-iodide on reaction with $HI$ (excess)?

What is the product of the reaction between $CH_3ONa$ and $CH_3CH_2Br$?
