Lời giải chi tiết

a)

$C{H_2}OH{\left( {CHOH} \right)_4}CHO + B{r_2} + {H_2}O \to C{H_2}OH{\left( {CHOH} \right)_4}COOH + 2HBr$ 

b,

$\eqalign{ & C{H_2}OH - {\left( {CHOH} \right)_3} - C - C{H_2}OH + {H_2}\buildrel {Ni,t^\circ } \over \longrightarrow C{H_2}OH - {\left( {CHOH} \right)_4} - C{H_2}OH \cr  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\;\left\| {} \right. \cr  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\;O \cr}$

c,

$\eqalign{ & C{H_2}OH - {\left( {CHOH} \right)_3} - C - C{H_2}OH \mathbin{\lower.3ex\hbox{$\buildrel\textstyle\rightarrow\over {\smash{\leftarrow}\vphantom{_{\vbox to.5ex{\vss}}}}$}} C{H_2}OH - {\left( {CHOH} \right)_4} - CHO \cr  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\;\;\;\;\;\;\;\left\| {} \right. \cr  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\;\;\;\;\;\;O \cr}$

$\eqalign{ & C{H_2}OH - {\left( {CHOH} \right)_4} - CHO + 2\left[ {Ag{{\left( {N{H_3}} \right)}_2}} \right]OH\buildrel {t^\circ } \over \longrightarrow C{H_2}OH{\left( {CHOH} \right)_4}COON{H_4} + 2Ag \downarrow + 3N{H_3} + {H_2}O. \cr  & \cr}$

d, 

$\eqalign{ & C{H_2}OH - {\left( {CHOH} \right)_4} - CHO + 2\left[ {Ag{{\left( {N{H_3}} \right)}_2}} \right]OH\buildrel {t^\circ } \over \longrightarrow C{H_2}OH{\left( {CHOH} \right)_4}COON{H_4} + 2Ag \downarrow + 3N{H_3} + {H_2}O. \cr  & \cr}$
