Question: The equation for the initial reaction between an alcohol (primary or secondary) and iodine solution in the presence of aqueous sodium hydroxide is: RCH(OH)R'() +

The equation for the initial reaction between an alcohol (primary or secondary) and iodine solution in the presence of aqueous sodium hydroxide is:
RCH(OH)R'() + I2(aq) + 2NaOH(aq)  RCOR'(aq) + 2NaI(aq) + 2H2O()
where R and R' = H, alkyl or aryl group
i. According to the equation, which alcohols should react with the hypoiodite solution?
ii. Use the equation to explain why certain alcohols are able to give a positive iodoform reaction.
iii. Why does ethanol give a positive iodoform test but methanol does not? (Hint: look at the reaction equation).
