Tablet powder containing ca. 0.25 g of furosemide (frusemide) is shaken with 300ml of 0.1 M NaOH to extract the acidic furosemide (frusemide). The extract is then made up to 500 ml with 0.1 M NaOH. A portion of the extract is filtered and 5 ml of the filtrate is made up to 250 ml with 0.1M NaOH. The absorbance of the diluted extract is measured at 271 nm. The A (1%, 1cm) value at 271 nm is 580 in basic solution. From the data below calculate the % of stated content in a sample of furosemide tablets: Stated content per tablet; 40 mg of furosemide (frusemide) Weight of 20 tablets = 1.656 g Weight of tablet powder taken for assay = 0.5195 g Absorbance reading = 0.596

Draw the structure of a four-residue segment of DNA with the following sequence.

(3' end) G-T-A-C (5' end)

Rank the species below in order of increasing nucleophilicity in hydroxylic solvents:


CH3CO2-, CH3S-, HO-, H2O.

Compound A, C6H12, was found to be optically active. On catalytic reduction over a palladium catalyst, one equivalent of hydrogen was absorbed, yielding compound B, C6H14. When compound A was treated with KMnO4 in an acidic condition, CO2 bubbled out and compound C was formed. Compound C has the formula C5H10O2 and it is an optically active carboxylic acid. Draw the condensed structural formula and state the IUPAC name of compound A, B and C.
