formulae of acid RCOOH

Alcohol one ROH

Answer 2

$\huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

a) Hydrogenation reaction is used in the conversion of vegetable oils to fats.

Chemical Reaction

$C_{2}H_{6}\: (ethane) + Nickel (catalyst) ==> C_{2}H_{4}\: (ethene)$

b) You have not provided the complete question

Suppose the ester formed is ethyl ethanoate $( CH_{3}COOC_{2}H_{5} )$

We used Ethanol $( C_{2}H_{5}OH)$ and ethanoic acid $( CH_{3}COOH)$ for the preparation of the given ester

Catalysts used: strong acid such as$H_{2}SO_{4}$

What is catalyst?

Catalyst are the substances that cause a reaction to occur or proceed without the reaction itself being affected. Example: Nickel, palladium etc.
