Maleic acid has applications in the food industry and also in drug stabilisation. It is the cis-isomer of butenedioic acid, and its structural formula is $\text{HO}_2\text{CCH}=\text{CHCO}_2\text{H}$. What product is produced when maleic acid reacts with cold, dilute, acidified manganate(VII) ions?
- A$\text{HO}_2\text{CCH(OH)CH(OH)CO}_2\text{H}$
- B$\text{HO}_2\text{CCO}_2\text{H}$
- C$\text{HO}_2\text{CCH}_2\text{CH(OH)CO}_2\text{H}$
- D$\text{HO}_2\text{CCOCO}_2\text{H}$
