Write the equations for the reaction between: a) Phenol and hydrobromic acid b) Glycerin and nitric acid c) Ethanol and sodium

a) phenols do not interact with acids, because themselves are a weak acid. With the exception of nitric acid of course
b) Ch2 (OH) -CH (OH) -CH2 (OH) + 3HNO3 = NO2-O-CH2-CH (-O-NO2) -CH2-O-NO2 + 3H2O (reaction occurs in the presence of H2SO4)
c) 2CH3-CH2-OH + 2Na = 2CH3-CH2-ONa + H2
