Medium

Complete combustion of 0.00300 mol of an organic acid produced 0.0120 mol of carbon dioxide.

The same amount of the acid required 15.0 cm3 of 0.100 mol dm-3 Ba(OH)2 (aq)\text{Ba(OH)}_2\text{ (aq)}Ba(OH)2​ (aq) for neutralisation.

Which could be the formula of the acid?

HOOCCH2CH2COOH\text{HOOCCH}_2\text{CH}_2\text{COOH}HOOCCH2​CH2​COOH

CH3CH2CH2COOH\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}CH3​CH2​CH2​COOH

HOOCCH2COOH\text{HOOCCH}_2\text{COOH}HOOCCH2​COOH

CH3CH2COOH\text{CH}_3\text{CH}_2\text{COOH}CH3​CH2​COOH
