a. 

b. 

$CH_3COOCH_2CH_2CH(CH_3)_2+H_2O \overset{{{H_2SO_4},t^o}}{\leftrightarrows}CH_3COOH+(CH_3)_2CHCH_2CH_2OH$

$CH_3COOCH_2CH_2CH(CH_3)_2+H_2O \overset{{{H_2SO_4},t^o}}{\leftrightarrows}(CH_3)_2CHCH_2CH_2COOH+CH_3OH$

$C_6H_5OOCH_3+NaOH \xrightarrow{{{H_2O},{t}^{o}}} C_6H_5COONa+CH_3OH$

$C_6H_5OOCH_3+NaOH \xrightarrow{{{H_2O},{t}^{o}}} C_6H_5OH+H_2O$
