Make up the equations for the reactions of interaction: a) methanol and potassium

Make up the equations for the reactions of interaction: a) methanol and potassium, b) methyl ester of methanoic acid and water, c) glucose and hydrogen, d) formic acid and sodium hydroxide.

Let’s compose the reaction equations:
a) 2CH3OH + 2K = 2CH3OK + H2 – the substitution reaction occurs according to the functional group – OH, potassium methoxide is formed;
b) НСООСН3 + Н2О = НСООН + СН3ОН – hydrolysis of methyl formate, methanol and formic acid are formed;
c) СН2ОН – (СНОН) 4 – СОН + Н2 = СН2ОН – (СНОН) 4 – СН2ОН – reduction reaction, sorbitol is formed;
d) НСООН + NaOH = HCOONa + H2O – exchange reaction, sodium methoxide is formed;
Glucose is an aldehyde alcohol, the hydrogen addition reaction is possible at the carbonyl group – СОН.
