Question

Complete the following reactions:

(I) CH3COOH + NaOH →

(ii) 

(iii) CH₃OH + O₂ \(\underset{MoO_3}{\stackrel{873-923 k}{\longrightarrow}}\)

(iv) CH₂ = CH₂ +Br →

(v) CH₃COOC₂H₅ + NaOH →

(vi) CH₂ = CH₂ + H₂O \(\overset{H_2SO_4}\longrightarrow\)

Answer 1

(i) This is an example of neutralization reaction 

CH₃COOH + NaOH → CH₃COONa + H₂O 

(iii) Alcohols will get oxidised to acids in the presence of MoO₃ which is an oxidising agent. In this case, methanol (CH₃OH) gets oxidised to methanoic acid (HCOOH). 

CH₃OH +O₂  \(\underset{MoO_3}{\stackrel{873-923 k}{\longrightarrow}}\) HCOOH

(iv) CH₂ = CH₂ + Br → CH₂Br—CH₂Br 

This is an example of addition reaction. 

(v) CH₃COOC₂H₅ + NaOH → CH₃COOH + C₂H₅OH 

This is an example of saponification reaction and is used in the preparation of soaps. 

(vi) CH₂ = CH₂ +H₂O \(\overset{H_2SO_4}\longrightarrow\) CH₃-CH₂-OH

This is an addition reaction, where H⁺ is added to one of the carbon and OH^- is added to the other carbon.
